Ok I just did a log tonight after working all day to get my fuel trims good and what happened was not normal for my car, first off I normally boost around 17psi but had turned up my boost a tad and ended up at 22psi and around 5500RPM I started blowing a little white smoke out the exhaust(Is this just fuel) It never smoked driving normal or ay 17psi. And the CRAZY thing I noticed about this log was my timing was being pulled and I had zero knock, the car felt like it was cutting back a tad around 5000+ rpm and then I looked at the RPM's on my log and noticed this(RPM going up and down).

I let off at 5300rpm because I saw the white exhaust smoke, this was 3rd gear.

I then turned the boost down to 16psi and added 3% fuel accross the Hi and was still pulling Timing,,,WHY???? :confused: :cry: :(

Any ideas why I am pulling Timeing,
 
Something's not right. You're timing should drop down as boost hit's and then climb back up till redline.

Have you checked your base Timing?

PS white smoke isn't Fuel...
 
I had checked my base time a month ago and it was perfect, I since advanced it a little, I was told I should do that because I had zero knock. Could this be the problem??? I will retard it a little and go make another log.

About the white smoke, like I said it was doing it at 22psi but since I lowered psi to 17psi and now it is not doing it anymore(for now at least). :(
 
Ok, I fixed the timing advancing problem, I had to retard the timing a little and it is advancing perfect now. But now I have a new problem, I hit fuel cut for the first time ever, and the sucky thing is I just got my fuel trims almost perfect, so I either have to run bad trims(to lean) or run good trims and be to rich and hit fuel cut. :cry:
