I know what you're thinking. No way! However, I've been using the EFIlive SD tuning program to tune my 02-C5. All has gone well except now I'm trying to tune my WOT using the VE and PE tables. I'm trying to set the AFR at 13.0 but the best I've done is 12.5. I've tried all kind of combinations that I'm too embarrassed to mention, but nothing seems to help.
Are there any suggestions? I hope you can help. I'm going racing this weekend.
Thanks for your help.
Tony
