My dyno tune results...
The best thing that PD1 did to this car was dyno it in 4th gear. This is the best gear to dyno in. It puts the most load on the car and allows the ECU time to collect very rich data.
When I get access to a dyno I will ONLY tune cars in 4th gear. Thumbs up way up to pd1.
Second, you need injectors when you have a TBE w/tp and an open element filter and you are using the ECU to control boost. ECU boost control holds at least 2 more psi up top than an MBC. That requires more fuel and the stock injectors get maxed out and you lose control over the AFR. I have had that happen to a lot of Evos that I have tuned.
Third, you need a baseline dyno to judge the gains on this car rather than look at peak numbers. These numbers mean nothing since there was no baseline done. I do understand that the injectors were not scaled for a baseline, but that could have been fixed by using a baseline injector scaling/latency for a base dyno pull. After that you can scale the injectors to perfection and go from there. That is what I do when a custoemr has injectors and wants a baseline.
Peak numbers are for the never ending e-***** contests...but gains are what really counts in a tune. Since there is no baseline on the car, then we do not know how much power the car gained.

I personally use an Apex AVCR which I peak 24psi and hold 23psi. Anyone who knows how to properly set up a AVCR knows how to do this. And I have NEVER lost control of the AFR and never maxxed my stock Evo IX injectors.
Even at 30psi tapering to 27psi on 100 Octane it's never happened...
You should not be tuning cars at all if you can't control your AFRs on an Evo IX with just a TBE and open element filter reguardless of what is controlling boost.
This is also my final post in this section.
I've worked on car for a very long time, and probably tuned much more cars then you have. I've tuned over 50 different Evos on a dynapack for the shop I used to work at. All baselining around 260 and ending up north of 320whp with basic mods with several topping 350whp.
Just because I don't post on the forums much doesn't mean I don't know what I'm talking about.
You say every car is different, some stronger some weaker. I agree and his at it's current state is weaker. How many stock evolutions have you dyno'd personally and then retuned? Out of the 50+ I did almost every single one baselined right in line with the others.
And if it is your shop that did the work, why did he install 750 injectors?
But I can't argue with your point that under 300whp tuned at your shop is in line. It is your shop and since its probably the same tuner, you will probably get the same results.
The weight does change the numbers and unless you or the tuner weights 300 pounds, why do you use 3500?

Funny how I just happened to be crusing through this thread, read this post, and kind of chuckled.
If certain people only knew. But, Like Bryan said, this will probably be my one and only post in this thread, never to return either.
Bryan, don't get worked up over this, your input is valued too much over in other forums.

Wow you lost control of the AFR in a lot of Evo's you tuned because you maxxed your injectors? O_o

Also, ease up, Sky. It seems like you need a hug.

Oh man I wasn't going to post again but I just had to. You guys are awesome. 
That's not he same car so it won't apply. Also that car is only running 17psi peak. Meaning it probably fell to like 12-14 psi at redline where the tuned car is running around 20psi. The raise in boost and leaning it out alone would bring up the gains between the 2 cars. Did you even tune the mivec on this car?
Are you kidding me? Have you tuned an Evo? Who has tuned their AFR so rich on a IX with basic bolt ons that it causes the IDCs to go through the roof just to avoid knock.
We already know that. My 280 on a DD with just a tune and dp was on **** so cal 91 oct as well.

A comment worthy of someone who doesn't even know if their shocks are blown.

Stock injectors will max out with TBE w/tp and an intake using ECU boost control. I am not the only one that has experienced this. Razrolab, for example, have had the same experience.
This has been documented and logged many times over. There is really no room to argue this point.
This has been documented and logs have been posted many times.
If you have data proving otherwise, then please post it. If you do not have data, then you are talking out of your ***.

I wasn't going to touch this thread again, but ignorant statements like this just need to be addressed.
Says the guy that brought up a BR tuned car in this thread...
Now I am really done.

I have never heard that. I may try and see how it goes.
No the car ended having a fuel leak the night before and it could not be fixed that last minute.
Hope all is well at the shop Dan.

I hit 249 to the wheels on Buschur's dyno,
I don't even have a boost controller, had it the same way for 2 years now since I drove it off the lot with 3 miles on the clock, completely stock. figure i'd put my 2 cents in with talk of stock evo's
