Trifecta tune has a tune. Haven't heard any results though. Check their website and see what you can find. I believe it is like $300!
I have the Trifecta tune on my Regal, and it wakes the care up big time. I also run E85 which adds a little extra on top of the 93 oct tune. The car detects fuel as it normally does so I can still switch back and forth from gas to corn when I dont make it to a e station. I have been using Vince's(Trifecta) for years. Check out his site and let me know if you have any other questions. Service is very good. There have been issues not related to the tune that Vince has helped me find. My Buick had a cooling issue that the dealer said was no biggie. Turned out to be my fuse block was missing pins, so car would slightly over heat. Vince helped me work through the issue so I could relay the facts to the dealer and they did fix it. I did not tell them how I found the issue..lol Vince did not have to help but he did.Trifecta tune has a tune. Haven't heard any results though. Check their website and see what you can find.
