[QUOTE="SDMF, post: 488662, member: 412"] Programmers in a diesel can gain you some. Programmers in a normally aspirated gas engine can't gain you much, might be able to eek a bit MPG out of a turbo gas motor by delaying and/or limiting boost. Newer gas motors w/VVT already do pretty much all of the "old-tricks" for both more MPG and more HP by automatically advancing or retarding timing on the fly. With what gas engines can do on their own regarding timing and better fuel atomization it doesn't matter if you're driving a 1K HP F-1 car, ~700HP Indy/nascar cars, or a 250-400HP 1/2tn pickup, fuel saving measures are all the same. Easy into the throttle, let off earlier and coast more. [/QUOTE]
