Blue smoke on up shift
I just noticed that I get a small puff of blue smoke when up shifting after a high speed corner at the track. I only notice it from gear 4 to 5. I exit the turn at 5k in 4th, as soon as I jab the throttle when in 5th I get a quick puff of blue out the back. I don't notice the smoke anywhere else, not on braking, downshifts, or accelerating after braking. My PCV breathers from the valve cover are not routed back into the engine.
Cold engine compression with throttle open
Cyl1 - 165
Cyl2 - 165
Cyl3 - 163
Cyl4 - 162
Any thoughts?

It looked blue from the rear view mirror. I'll have to have someone follow me to confirm next time. The vette I was pulling away from didn't seem like he wanted to talk after. Even after noticing it and alternating between wot and 0% I could not get smoke. Only during that one spot on the track between 4th and 5th...maybe the angle of the sun at the time.
As far as I can tell, accel enrichment seem to be spot on as the AFR gauge shows 11.2-11.5 right as I get on the gas.
I'll keep an eye on it further.
