Trifecta mail tune??

[2boosted]

Vince at Trifecta is a Great Guy. Deal with him once I had a turbo Camaro LT1. Good Guy, Good tuner. But then Again I moved to Nelson for the Tune on my trucks.

emmerich5.3, for the sound of ur problem, looks like a vacuum leak.....I had that Problem once, and I just wanted to set the truck in flames, No matter how the tune was moved, I could not make it idle, and the Extra air kept it rich in spots I did not want to.......try a smoke leak detector....u'll be surprised !

Thanks I'll have to check that out. Kinda weird though it didn't start doing it till I got a retune. But then again I agree, it doesn't really make sense for it to be the tune. Also, I live at 5000 ft. I always wondered how he tunes for the altitude difference without actually seeing data.
