Hey everyone,
Recently bought an R32 GTS-4 which I'm pretty happy with. It however has a few little issues I would really love to fix up to get it running 100%. These are:
1) Car won't pull hard all the way to redline, it boosts perfectly in the mid-range but over about 4500rpm the rate of acceleration is much slower than getting up to 4500. Was told this could be because the car is running really rich or something? Any ideas? I have a feeling it could be ignition related, coilpacks?
2) Car sometimes makes a backfire type noise when I put the pedal down about half way, and say rev to 3000, then quickly put the clutch in to change. Could this be because of the car running rich and having excess fuel there?? Not sure if this is a backfire or "missfire".
3) The car has some kind of heavy duty clutch, and when I put the pedal in really quickly it will sometimes stall. However if I put the pedal in more gradually, it won't. Sometimes it'll go down to 0rpm and everything will cut out then it'll come back on by itself, sometimes it'll just stall and Ihave to turn ignition on again.
Would taking the car to a dyno tuner rectify my problems?
Thanks
EDIT - Forgot to mention, the car is pretty much stock apart from a Kakimoto 3" turbo back system. Still has stock air box, and boost etc.
