Here is my problem. I recently bought a 1995 PSD crew cab long bed dually. It has straight exhaust, but I odnt know what program its using. I dont believe it to be stock. My father has a 97 and has a super tuner. We tried putting the super tuner program into my truck, but at the end it says unable to download ol program or similar. Whats the deal?


And on a side note, what IS the best chip/tuner to buy? It doesnt have to be one of the program on the fly things, I just want to get the most out of my truck AND keep it in one piece.


95 Crew cab dually PSD, 36 ft. Riviera Camper, tows many cars, buildings, dozer, skidloaders, etc....
