Thanks everyone for the help! So what I gather from this is check my boost guage for accuracy, than check for boost leaks. And this is what my car should be putting down at this altitude 5800 ft and on 91 octane?

 

Honestly, I think you should see ~20 more whp than your posted chart (above). I'd leave the final word to Al though.

My 2cents.

 

Here - after a few pulls done without proper time to cool off the a/f goes super rich - way too rich

This is why its important to monitor the coolant temps through OBD II when you dyno as when you dyno with hot coolant the results are NOT accurate to the road

 

On 93 octane and at sea level where I dyno - the average range is 330 - 335 for his mods

There must be some discount for the 91 octane and the high altitute - to me 324 whp is about what I would expect

Don't forget - through the mail flashes are always about 10 whp less than a custom flash to account fo rcar to car variance

 

That is what I was hoping for as well.

So Al this is the power I am supposed to be making? Because if it is than it is what it is. But if you think there could be something stupid like a boost leak than I will look into it. thanks

 

How does that explain my stage 2 car making nearly identical numbers to his? If you look at the 7K+ RPM range of his graph you can see the power start to fall off, where my car (even w/ stock cams) does not taper to 7600.

This is also with your flash.

BR Stage 2 w/ Walbro fuel pump on 91 Octane:

 

Very consistant resulyts between the two cars - a/f curve looks similar and power bands look good

 

Al he was also making that power without cams? That doesn't make sense to me?

 

His dyno sheet was on the strong side.

Personally, I have no issues with 324 whp on 91 octane fuel and high altitude

If you want more power - check the boost as I have suggested

Leaning it out further with 91 octane is not adviseable - IMHO

With a custom tune another 5 - 10 whp could be squeezed at the same boost point

BTW - for informational purposes THE MOST WHP I ever made with those limited mods was approx 335 whp on 93 octane. That is the max on a dyno jet.

If you are saying that you are missing that last 10 whp - I am sorry - but its not reliaistic with your mods, fuel, elevation and a mail in flash

If your not satisfied - send it back in and I will refund your payment and flash it back to stock

 

Cool thanks AL, that is all I was looking for. It is hard out here when the only EVO tuning shop has only been around a couple years. Options are very limited.

PS would alcohol injection/injectors and a custom tune do alot for my car?

 

The main issue for me is how the car is feeling on the road and how it does at the track - you dont drive on dynos.

Injectors are not needed you have more than enough fuel

The alcohol kit would allow us to run 24 psi and a lot more timing - should be good for 350 whp with your mods

 

Good to know. I think my next purchase will be, have been debating for a while, alcohol injection and 10.5 hotside. Oh and rally the troops for you to come out to Colorado for custom tunes!!!!

 

I think 324 WHP is good power on 91 octane. I am getting around that with similar kind of mods. THats at 22 psi on11.5 A/F. Should not discount the variances of dynos, altitude and correction factors. We should stop comparing dynocharts cause I did that earlier when tuning my Evo 8 and honestly, wasn't worth it. I'm convinced its running as good as any others on the same fuel and the turbo's not going to give me anymore unless I run race fuel. If the car runs great, I wouldn't worry too much. Anyway, your power curve looks strong like what Al says..

 

I agree I think I was just hoping for more. And the shop I went to was telling me that something was wrong. By the way, what I didn't include is one of there cars tuned by that shop was towed away from the track (engine problems; would start and stall out...bunch of smoke being coughed out) on Sunday.

 

Here is my opinion on this topic. You can take it or leave it, just sharing an idea.

First of all, Turbo13 and JustDSM have two totally different setups. BR stage 2 vs. a mish-mash of parts (B&B exhaust/HKS intake). It is very possible that the BR parts actually work better together and have more power potential than the parts on Turbo13's car.

Next, you are comparing dyno runs on different days. Even with the correction factor this is not an accurate comparison.

Also, I am SURE that AL has done several custom tunes on a BR stage 2. He probably used this data to come up with a safe TTM tune for BR stage 2 cars that is very similar to the full-power custom tunes. I DOUBT that AL has done a custom tune on the exact setup that Turbo13 is running, so his TTM flash is based on a car with "similar" mods. There is necessarily more room for safety built into this flash.

I bet that if both cars were custom tuned that we would see bigger gains on Turbo13's car compared to JustDSM's car.

BTW, Buschur got 320hp/329tq on their stage 2 car using 94 octane and near sea level. Taking that into consideration, I think that what Turbo13 is making on 91 octane and at high elevation is respectable and exepected.

JMO, AL please chime in if I was way off on the flashing subject.
