it also does not misfire. i dont have any codes. AND when its idling, the car has a small shake to it. the RPM moves ALITTLE unstabily
recently got stage 1 unitronic. it drives normal. at high rpm's when im hitting it hard it stutters a couple of times and doesnt give full acceleration and boost. i just changed spark plugs and maf is clean.
WHAT IS WRONG?!?!?!
