The Nissan Power Pup was designed for Nissan Titan owners looking for more power and better fuel economy. The Nissan Power Pup offers the user two different engine tunes above Stock to accommodate various driving conditions: Regular Tune (use with regular fuel) and Premium Tune (use with high-octane fuel). It also gives the user the capabilities to adjust rev and speed limiters, as well as read and erase diagnostic trouble codes.
What I'm after is the fuel savings. I'm not so interested in the premium tune to get max hp... I'm also not interested in rev limiters or speed limiters as I never even come close to those limits. Actually, I don't need the diagnostic code reading either.. I'm just looking for the fuel economy.
I'm curious to know if anyone has used one of these?
I've heard great reviews from the Altima Coupe guys... They have CVT also, so I know that's not an issue.
