hi all,
I was wondering, is it normal, when my turbo comes on boost, for a puff of blackish soot like smoke to come out of the exhaust?
i think ive seen it happen on some high power skyline videos on youtube.

Cheers

James.

I noticed was my gtr doing this. It had a missfire (which would come and go) but would allways throw out overfuelling smoke even when I didn't feel the missfire.

I changed all the coil packs for brand new and not only does the car go so much better (a lot better than when I used to think it was going ok when not even missing) but I can't notice the overfuelling smoke anymore.

ive always been happy to see a puff of black smoke on hard accelleration in my cars. id rather be running a bit rich than a bit lean.

skyline doesnt do it though. going on the rollers tomorrow so we'll see whats going on then:thumbsup:
