Had car at tuner and results were 430 at the wheels at 5000 bc air fuel went lean. He could not tell me what the cause definitely is but pointed out fuel rails as possible cause. I am running a 255 high pressure, stock lines, and rails, fuel pressure is set at 40 and i feel i have plenty of injector as duty cycle has not been pushed. i am running a 90 mm lightning mass air and not sure at what hp this can get pegged. running low psi 6 to 7. with e303 cam. this combo b4 stroker motor w/ 306 made power w/ good AF to 5800 but making only 400 at wheels.
Any help would be apreciated
