I'm looking at GTP38R, and wanted to get some input from anyone who has uprgraded from stock with this turbo. How much difference did it make? Lot more power? What about MPG if ya take it easy with it?
Can't help you much with this as I added injectors at the same time and some other stuff. Did these additions make a difference in power? Yes!! As far as the MPG's go, cruising or towing I don't see alot of difference. I have a hard time keeping my foot out of it around town so it is hard to tell there.
