I have been having problems with engine since head and cam swap and transplanted engine. It did have a mail order tune. It wasn't the tuners fault the mechanic who set up the engine screwed a few things up. I tried many peoples ideas with nothing helping. There are no dyno shops near by to make it easy. I contacted Trifecta and they sent me their GT Tuner. I know I drove Vince nuts with numberous e-mails. But he quickly answered them all and after recording and e-mailing my car's program he began tweaking it and narrowing down the problems. Now the car is awesome, and it was cheaper and easier than me hauling the car to a dyno shop. Thank you so much for all your help Vince. Trifecta is awesome.
