Re: LT1 tuning help
 
Darrel, you're doing great. Learn about the car and EFI in general with the system you just paid for. Once you've made the car as fast as it can go
with that system, and you're thinking about buying a new one, wait 30 more days and there will be a better one, etc. etc. You've done a great
job as a driver. Stick with your strengths and budget to upgrade in the
2018 season. J.R.

That is pretty close. Won't find a lot of horsepower either, but the potential to find more will be there. You can do individual fuel trim per cylinder, can also do sequential injection with some legal mods inside the Optispark. Will also let you change injector vs. intake valve timing........ Datalogging is built-in and is far better than most other EFI systems, only a Racepak would be better but is not needed.

FAST XFI has all that. I have worked a lot with both. Most of the fast Super Stock LT1s are using FAST.

I am very familiar with tuning the LT1. I have many programs as well
I will be in Vegas Tomorrow(Tuesday) for the makeup race and regular Div7 race.
I would be happy to help you with it.

Thanks JR. Good advice. Now whether I'll use it remains to be seen but I'm very conservative and have a tough time spending money on something I don't have to have other than obviously buying a race car. ;)
