I bought a 90 gt with a paxton supercharger on it 2 weeks ago.And the acceleration is reallly bad at the low RPMs. If i stomp on the gas it really flys. Idk if that is just how it works but it doesnt feel right. It just started doing this 3 days ago so what could it be. It feels like it could possibly be the clutch cable ???? When i down shift it takes a sec to go down. Example if im driving in 4th at 3000 rpms and downshift to 3rd it will take like 2 or 3 seconds to get to the correct rpms it should be at , it will go back to 1000 (neutral) then go to what its supposed to be at.( im not changing the speed im driving)

 

Sounds like you need to stop beating the he'll out of it and bring it to a professional shop. To me it sounds like a pretty severe tuning issue

 

Well i dont beat the hell out of it. I take good care of my cars actually. I've only had the car for 2 weeks so the guy before me probably beat the hell out of it.
