Did you try adding 100-150 rpm to the AC On columns in B4603...?

It's still stumbling rich under a load in higher gears at 1500-2000, but then I'm basically leaning it out for it to be lean at those MAPs in other gears or different driving situations.
Just going in circles, it seems.
What is causing it, and how do I fix it?
Do you have a log of this...?Originally Posted by Jim_PA
Attached tune was altered based on attached log file.
I filtered the log for > 30% TP, > 65 MPH, RPM < 2500 (Shows BEN's .85-.93 in many cells)
Then filtered for:
MPH < 50, RPM < 2500 (Shows BEN's > 1 in a lot of the same cells)
Boost-Base_027.ctz
LS1B_0142.efi
I haven't switched out my 02 sensor in a while, maybe I'm due for a fresh one?
How many miles on your O2S...?

I'm still looking thru your files, I've been slowed up, sorry.
40,000 miles or so. I'm in no hurry!
I have the car running really well. It's been great all fall and winter. Now that temps are creeping up, I started getting P2101 codes again when I'm heavy on the throttle in the upper RPM range. This happens when the car has sat for a little bit and heat soaked.
Something is going awry ONLY when the air is hot. I haven't had this happen since September and I drive it every day of the week.
I do apologize, I had some family hospital stuff going on. When I last looked at your log/tune files you seemed to be on the right track (and you will know this when engine response/driveability is good).
