I searched around, but didn't really find what I was looking for. I have been using hptuners for a while now, but I feel like I may want to try EFI. The car is a supercharged corvette making a little over 800whp. My reason for switching is I have 96lb low impedence injectors and I have not been able to get them to idle that great and it doesn't seem like anyone knows how to help or is willing to that uses HP. I have seen multiple people using EFI with good results and it would be worth it to me just to get it right by switching over. My main concern is will my cars pcm have to be reflashed to stock or can I start making changes immediately with the new software? Oh and if anyone has any pointers on the 96ers let me know.
