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????
