Hi guys,
I'm using the tuning school's GM beginner book to tune my nova with a 5.3 (cammed with 224/224 110 LSA). I tuned the VE table and my LTFT were a respectable -3 to 0. I moved on to MAF tuning and it's been a bumpy ride so far. During testing and datalogging the car runs okay in gear but upon return to idle it often stumbles (my wideband shows a very rich condition ~ 10.0) and sometimes dies. I'm attaching my tune file and log file for my last test. thanks in advance for the help.
