Economy tune
I know there's some guys on here running programmers and I need some advice. I've been running the performance tune on my truck ever since I got the programmer and love the power. But ever since I got the 3.92's put in, I've noticed a drop in gas mileage.
No I haven't calculated it but it is definately a noticeable drop. Driving to Norman and back for work has been killing me, to much damn money to be burning premium. So my question is, have any of you ran the economy tune vs the performace tune and notice any difference in fuel mileage?
I don't want to lose the power but if it'll save me some money, I'll do it until I take it back to the track.
