While giving the car a bit of 'right pedal' yesterday, the engine seemed to be slightly stalling/juddering type thing (for want of a better expression). Ran fine under normal driving but when accelerating hard I had to loosen off the pedal a bit as it just wasn`t boosting smothly at all. (hope this makes sense).
This was on stock boost with the controller off and was peaking about 1.6 bar. Normally runs on just under a bar.
It`s a J-spec and I have the basic normal bpu modifications and the auto box.
My questions are:
a) If a restrictor ring has been fitted, will I be able to see evidence of it without taking the exhaust apart. It`s a Nur-spec R
b) Would one be advised/recommended.
c) Do any of our traders supply them.
d) It also seems to be more powerful since installing the bov. Am I dreaming or is this normal.
e) I`ve just installed IK22s. Should I ditch them for 24s
Thanks guys,
Andy
