If I go with IDP what tunes and also from gogo
Yeah I'm looking at the same problem: headgasket failure. I was looking at a SCT SF3 ($379.99) from XtremeDiesel.com and an SCT X3 ($429.99) from InnovativeDiesel.com. I like the SF3 because it has slightly more horsepower at full gain (and its cheaper), but I was worried about the transmission and gas mileage, and of course, them dang headgaskets! So which will shift smoother, which will give more MPGs, and which will conserve my headgaskets better? THANKS
