Just a quick update - This morning car started up perfectly normal warm idle at ~825 rpm AFR back to 13.5 while I putzed around town for the first 15 minutes - did an ~100 mile drive up the mountains - man it was nice! Got to my lunch spot after being on the road about 75 minutes, elevation likely 7000 ish - and the car was idling with AFRs at about 12.9. Came back and park her in the garage back to 14.1 idle speed ~850. Is this normal to have these fluctuations? Magical mysteries of CIS?

I think I need to lean out my cruise a little - been pretty consistent at about 13.5. Boost is 10.0 - need to address that.

One last thing - when, say in 3rd gear, accelerating from low rpm, pedal down all the way and when you get up in the revs to say 4000 or 5000 and you let off, even smoothely, but a little quickly, the engine bucks - is this a sign of richness? or? Note - the 964 Turbo uses a different BPV setup than the 930 and I have a brand new 710N BPV, FWIW.

Any thoughts appreciated - TIA!
