Since I installe the GT30R. I haven't used anything above 3psi because I knew the tune would be off. But it wa WAY off. So I haven't had the chance to go any higher until this is solved. (4 months of this now)
Generic Precision 3.5' Core. 650hp rated (Kinda funny to me how they rate them) intercooler.

To clear things up: Vitesse just provided the software! The MAF sensor, Injectors, and the rest of the hardware parts were supplied by the customer.
A faulty MAF, Faulty TPS (not reading WOT, seen it when TPS gets hot), faulty ground, faulty fuel pump (if fuel pressure is dropping)..... Bad hose to Fuel Pressure...

but
MAF is brand new original product (not chineese)
TPS is brand new.
Injectors flowed and tested.
Pump has 20 miles on it and ran the car when It wen 123mph in quarter.
FAULTY ground. very possible and having a hell of a time looking for it. I don't think there is a wire I haven't checked for continuity or ohmed out less than three times in that harness.
Fuel pressure solid. Gauge inside car and on FPR. But. Will try another/better hose to Fuel pressure regulator. Sounds viable.

I've replaced all clips and cut wires back to healthy area and wired in new clips. Continuity and Ohmed. Verified haness using all methods. Idles great. runs great. would screw up in just one spot if this was the problem though. have always had resistors and worked perfectly on other set up. Even changed those out just in case.

THANKS GUYS. I've been working so hard for a while now to find this gremlin. I've covered so much ground in my investigation that I know there's not much left. I really am just looking for pitty at this point. It's pathetic, but it makes me feel better. It helps me step back, and gain energy later to try and fix it.
I'm completely re-wirig the Fuel side of things on the harness now. It checked out fine, but what the hell. I'll try the hose Sunday. I'll let ya know.

the trick would be to do it on stuff while acclerating past 3750. Then to know which wires to check. too difficult.

Im still confused on this whole thing.
Can you explain what you did at the dyno? When did you let off the gas?
Looking at the graph you posted you hit 3psi at 3k rpm and everything kinda goes flat. Obviously when you let off the throttle it should go really lean, so it makes it unclear when you let of the gas on the dyno. WHAT A/F did you see when you decided to take your foot off?

Option 1. Uhmm since you seem to be enjoying throwing money at the problem. I think you can get a new/aftermarket harness for around 6-7 hundred.....
Option 2. Sell all those parts you bought and pick yourself up a new stand alone and call it a day.

1. Something wrong with all or one of the injectrs somehow
2. injector driver is going bad for some reason.
3. could be the resistors screwing up the drivers.
