Hey man, I have seen your car being built all along the way, from the red to now your current setup. I have been a customer/now friend of Jimmys for 15 years. He is the most straight forward guy to deal with. He is a true racer at heart and only wants to see the cars leaving the shop at there best potential performance. He always bends over backwards for all his customers regardless of what car they have or who they are.

As far as the tuner on the Stock ECU. John tuned my car to running its best by far with the stock ECU over the AEM: Idle, Drivabilty, Spool-up , Top-end. He knows exactly what he is doing and is very innovative. And no matter how good a tuner is, there is only so much power they can "take away" before hurting something. If you car is not breaking, its probably hardware.

Kouzman's car I remember his dyno graph from the shops dd. It showed to be extremely laggy on the dyno, similar to yours, but ran 10's at 134 MPH on pump gas. You added parts to make it more laggy, bigger valves, Bigger intake.. then tried to choke the exhaust with a small back housing. In my 20 year of racing there are three things I learned about making power with parts. Combination, Combination and Combination.

Good luck with what ever you do, but no reason to bring try and bring a shop down that I have personally seen bend over backwards for you.

 

Kouzmans car was tuned with so much lag on purpose by the tuner. The parts I added to my car were the advice of the shop owner, as said above your friend for 15 years. Your car in this thread https://www.evolutionm.net/forums/ev...lid-power.html spooled up so much faster than mine. You had more parts that will create more lag than my setup, a terrible air fuel ratio, and you make more power than me by a good amount. Whats the deal?

 

2.3 Get ready for that short power band

 

Intake manifold, ported head, fp4r cams, .82 hotside and journal bearing

 

Wow how did I miss this thread!

I am glad to see that my car is used as a benchmark!

To the op... You pm'ed me too and I tried to explain some things...

First of all you are comparing three different cars... What makes you think that your car is similar to freddys or my car? Not in a bad or diminishing way... They are different!

Are you running a stroker with aluminum rods, high compression and custom head that Freddy had? I doubt it...

Do you run a stock bore, stock compression with very light internals, no balance shafts, very light Carrillo rods like mine? I doubt it... Also freddy gave you an answer regarding my head work... Nothing which helps on a pumpgas tune along with the stock manifold...

Yes my original graphs were a bit laggy... The car was tuned by junior then and we were using a mild tune since we built the motor... No mivec map, on the rich side, that both hurt spool...

As soon as I started raising the boost to. Lose to 30psi the car started to clear up top to proper aces in the mid 11s thus making much more power... Guess what! The car was trapping 134+ and was running 10s! Even with the basic map... If you have followed my threads you would have seen junior asking me to go back and tune it 100% so it can run even faster! Never had the time to do it, until he left the shop and I went back to stock turbo and ecu...

Ohhh yes... Ecu... Your maf will always restrict power. Period! It is physics... I was running on aem with a huge 100mm turbo inlet and a huge filter, the biggest I could fit... In other words, much less restriction, if any compare to the 3 inch Maf setup... Just from that, especially on a large turbo and lots of boost I would expect gains maybe in the 40-50 awhp range...

It seems that you are not comparing apples to apples...

And what the hell you expect when running a huge turbo like the fs635 on a sto k compression 2.0? To spool at 4000rpm? It will not happen! And don't bring buschurs car up! Again a different car!

Now about Jimmy. Jimmy in my opinion is a friend. His service is extraordinary, his work too... The only guy I would trust with my car and any other toy car I will buy. I am not certain what happened with you and him. Jimmy is proud for his work and his customers and their cars.

Even John that he tunes for Jimmy now, the stock ecu cars. Excellent service, the cars make power safely and they are drivable. Again even on the stock turbo I made plenty of power. 408awhp/445awhp torque on pump at 26psi max which again is above average I believe...

What Jimmy did for me? He built me a car that I could go to the track almost every weekend, run and drive it back, not come back on a flatbed... And everytime I would run in the 130s on snow tires... And when I put tires on, 10s every time until they would kick me out... And that's the reason I stopped because I didn't want to put a cage...

Good Luck with your quest my friend but you should spend more time educating yourself before starting such threads blasting on everything and everyone...

As far as the shop, my car, freddys, etc... The results with proof are just a hit of the search button away...

Be well

 

To me, this sound like bla bla bla. I want to blame you so I can make more power and not spend more money. Go buy your self a 35r, and a 2.3 if you want to spool at 4000 RPMS. It's not Jimmys fault that you have that set up.

Your car is lazy because your turbo sucks, don't blame them for your junk parts that you supplied. Change the turbo and it will be mint.
I just had my buddy junk his 6265 because of the same reason you have. It made no power. It sucked. I also had a 6262 in my car. It was terrible. A plain 35r is better.

As for the bumper thing, your on your own sorry to hear that. I just don't see Jimmy doing that, that's all.

 

sounds like i found another member of the "i hate precision turbo" club.

 

What are you talking about. In the thread that I posted where does it say Freddy was running a stroker in his evo? Get your facts straight before you post. I am running a fully built motor. I have Weisco pistons 1400 hd, Manley turbo tuff rods, AMS balance shafts, and a fully built head that is ported. Which you dont have. My motor is stock bore, stock compression. Freddys car was running on 93 octane pump gas just like my car. Freddys car was dynoed in very similar weather with a very poor air fuel ratio. And he spools up everywhere much sooner than me. Even though he has larger parts than on my car like turbo, intake manifold, etc. The difference is my car spools up much later than freddys because the tune on my car sucks. And then I was told by the shop owner and tuner that it could be my intercooler, cams, or turbo. Which is not the issue, because I was told my car was checked out by them, before the tune. And they both said everthing on my car is good including using a maf sensor, and that i shouldnt lose any power or spool up using it over a 4inch intake on a s.d. tune. And everything else on my car is ready to tune and make power.

 

Actually it is his fault, I have the parts I do on my car, because of his recommendations. When I asked the shop owner about the fs635 aka 6235 he said it was a great turbo. And I have not seen results that show the fs635 aka 6235 is a bad turbo to us on a evo.

 

You might be running a built motor, but you are not running freddys motor. I am not running freddys motor either... Freddy can give you the details... Differences thAt make freddys car unique... I don't want to say anything more about someone elses car... Freddy is a friend and he had a monster of an evo!!!

Also you are not running aem. Read again what I wrote about the restriction of the maf. Search in the forums... You will see how different a maf car is from an aem car, especially when you use a bigger turbo inlet pipe...

I could bet money that if you did aem with a big 4" turbo inlet and a big filter the car would make enormous difference... Staying with the maf you are compromising and you will never see the full potential... You could try stock ecu with speed density but I don't think you will like the drivability...

You have a bad attitude against everyone and anything and as you see we are trying to help... And that's THE SHOP way... Every post you make makes me realize why you are having issues with the particular shop. And let me tell you. With this attitude you will have issues with every shop...

Lastly, why didn't you post one of my latest vdrs on the fs635, and the way I was driving it at the track when they started kicking me out?



Do you think making more than 400awtq before 5500rpm is laggy? That's with around 31psi on straight pump and mid 11 afrs... And up top all hell breaks loose!!! And that's still with no mivec...

 

Well once again its not his fault. He's like everyone else that thinks Precision turbos are the **** but they are just ****. Trust me on this one they suck.
My 6262 on my 2.0L was very very lazy, its 100% just like yours. It made full boost close to 5800 RPM's. It made no power 530ish but it still went 10.30s at 133 to 138 mph. Then I swapped to an fp black and made 600hp same motor, same boost, same intercooler, injectors, pipes, same dyno, same everything just turbo change.
And no its has the HTA86 and oh man its a difference.,

Also I think Freddys car was always on a HTA82 then HTA86, thats like you having a fp red and saying why did his fp black make more power, you just cant compare them two at all. There is a reason why HTA turbos from fp are 500$ more than the precision simply because they are better.

 

6262 stock bore and compression full boost at 5,200 rpms Stock ecu s.d and drives awesome its all in the tune and combo period...Note not everyone can tune s.d like I mentioned before sure anyone can tune but how will it drive..As far as the op hes not happy you can't make someone happy if there not..

 

I dont have a bad attitude against everyone, I dont know why your saying that. But any way, like I said before both the tuner and shop ct owner told me using a maf would not be an issue. But your saying it is, I believe you and it makes sense, and I was thinking the same thing before I got tuned. But they both acted like it didnt matter. The tuner is not capable of tuning my car, s. d. on the stock ecu. So I was stuck with his recommendation of using the maf. When I asked about using aem to the tuner, I was told it would be a waste of time and money to tune with it, and that it would not be any better than using the stock ecu with a maf.

 

It makes sense 100%

There are numerous threads of big turbo cars on maf, almost sucking the honeycomb on high boost...

There is an AMS thread on an aem car, switching the turbo inlet pipe from 3" to 4" and gaining like 60awhp...

Also dynoflash had a similar experience...

Jimmy is an easy guy to work with, as well as John...

Best of luck

 

Freddys thread that I posted was when his car had a hta86 on it.
