Anyone use jet dst software?
I just bought a 04 avalanche and have added gibson shorty headers, race cats, true dual exhaust with an x flow muffler, airaid cad, tranny cooler, and corvette shift servos. My problem is that i have a z06 corvette cam and valve springs and was told i would need a tune to make it work, so i bought the jet chips dynamic spectrum tuning software and the S**T wont work, any one ever use it? is it worth a crap? or should i put it on ebay? computer geeks cant even get it to run on my laptop. any help would be great, i dont even know where to start
