Anybody else with stage 3 and above notice the idle as being a bit rough? Perfectly fine when cruising or accelerating (actually feels great)....just noticed after stage 3 that there is a little stutter during the idle and it feels a bit rough. Not a bad feeling, just wondering if it is normal or if it was just my car.

It's normal even without the stage 3. Lots of members have the same jerkiness at lower gears. It's just how the n63 motor behaves.

It was even more so than when it was stock. With stock, I know at low gears it had the jerkiness but since dinan stage 3, idling is even rough and stuttering. Like I said I don't mind, but wanted to find out if anybody else noticed the change

I never had a rough idle with S3 or S5, something does not sound right.

I have the stage 3, and i have the same problem. Engine feels Rough and Power lost.. 3 months ago the change my fuel injectors and when everything back to normal i felt this power back .... Now I'm getting the same problem.. definitely Power Lost!!!
I really think the injectors there a big time problem

No power lost on mine. Just rough idle when engine is cold. After a few minutes, it is pretty smooth. I had a drivetrain malfunction once and that is when te rough idle started (coincidentally that is when i did s3) but it never came back...I have since moved to s5 and no real change. I guess I will live with it until an injector goes out.

I have stage 4 and I def have the rough idle, doesn't bother me but at times I feel like I'm driving a 60's hotrod.
