97 gst no power top end
 

hey, Ive got a gst spyder, through all gears at high rpm it doesnt feel like its pulling at all!

I bought the link to find out... Ive got like 90%+ injector duty at lie 13lbs of boost.

I have a new 190lph rewire fuel pump
eov3 16g
turbo back exhaust
bov,
mbc,
link.

Ive been told the fuel filter could be a BIG PROBLEM is that so?!

Well it could be causing you to not get anough fuel i suppose.

Do you have a MBC set higher than 13lb? If so then maybe you have a little boost leak too.

RE: 97 gst no power top end
 

are you doing any tuning at all? Maybe you have a leak somewhere.

Im not sure if this will help but my car did that when I bought it. It would get it up to 4,500rpms, and just stop pulling and rpms wouldnt go any higher than that. I bought a fuel pump, injectors and SAFC-II and tuned it, everythings been fine ever since.

dsmlink?

stock injectors?

did it used to pull or has it always felt this way?

more story...

and 13psi is weak sauce for a 16g, turn to 15-16, more than safe with a 190lph fuel pump and stock injectors

Possibly could ur clutch be slipping at higher rpm. Isn't that a sign of a clutch that need to be replaced?

RE: 97 gst no power top end
 

well its depends if his rpms are rapping up or if the car is just not pulling
