2008 TBSS / LS2, largely stock, twin turbo, E85. I'm still working on the tune - I've got the VE and MAF pretty close (for street tuning), but occasionally this will occur. Step it down, and it will "flutter" at a certain point. It won't go any further unless I back out and try to get on it again...at which it will usually take off as it should. Tune and log attached...issue occurs at 00:42.
I'm also having issues with KR...but in weird areas. Also looks like burst knock, but I've got that disabled. So, if there's that jumps out, I'd appreciate the guidance.
