I've been having this problem for a while with my c5 corvette and I can't seem to figure out how to fix it. My car goes very lean on decel. I thought it might have been DFCO but I'm pretty sure I have it turned off. If someone could verify that for me I would appreciate it. The injector data is from Greg Banish so I'm not sure where or how to fix this. Any help is much appreciated. Thank you!
