my sr doesn't accelerate fast after 3.5 to 5.5 it gets there faster if i have my foot on the gas half ways. and when im on the freeway and floor it, doesn't really feel so powerfull. what could it be? it idles at 1200-1100 rpm,compression 155psi,fuel pressure 37-48,turbo spools freely and gets full boost at 3ish,timing 15deg, could it be CAS?

it could be a miss-adjusted TPS. if thats what it is, when you floor it the throttle opens too far and bogs/slows down acceleration. It could also be the throttle cable itself where it attaches to the TB.

Might explain why the car is idling high also

no its not throttle cable because i started the car with it disconnected and still idled high,tps i set it at .45V.

maybe when you put it wide open its starving for fuel... fuel filter, clean injectors? i doubt its ur guel pump i dont think... im pretty sure youd know if its the pump. how the condition of ur TB?
