engine is cutting out at 430hp help plz!! I have a 96 camaro lt1 with a rear mount turbo and an upgraded cam springs ect. stock bottom end heads intake. I've been to the tuner to have it tuned several times now and neither of us can figure out why the engine is cutting out. It cuts out at 4800 rpm at 7psi and 5500 rpm if i lower the boost to 5 psi. So it seems to be cutting out at a certain amount of air flow. Fuel pressure is good about 50 psi. It feels like the fuel is just being cut off when it hits a certain hp. Anybody have any ideas what could be wrong?? I'm so lost, ive tried new spark plugs, wires, opti, wastegate.

I'm running an in-tank 255 lph walbro fuel pump, 65# injectors, and aeromotive rising rate fuel pressure regulator. And yes new coil and plugs gapped at .032.
Th turbo is a T72 with a turbine .82. I bought it off ebay from cx racing says its capable of 500-700 hp. And is a turbine of .82 what you mean by drive pressure? if not how do i measure that?
Thanks for the help guys!

need to know actual turbine ind/exd.
like Louis is saying..... that ebay unit probably has something like an O-trim in it.... hence the problem
and even if they say it is something like a Q i would measure to make sure

Hopefully that helps.
It says its a P-Trim. And i meant .81 ar not .82.
I called the company up and there tech was a foreign guy that i couldn't hardly understand lol therefore no help there.
Is P trim what i want?

There were gapped at .035 and i gapped them down to .032 and no change what so ever. I'd rather try an upgraded coil first since last time it took me 14 hours to change my plugs and wires since i have to take my headers off to get to plugs 6 and 7..... stupid edelbrock headers!
