i dont think thats gonna get u better gas mileage....i bet u would get pissed off at that truck pretty quick, especially when some guy in a diesel goes waltzin on by you..:rofl:
mine is also close to being paid off, gonna enjoy that awhile n then buy another ec/sb lbz for my wife. diesel only for this guy, i had a gasser b4 my dmax and it looked n drove great but it had no power n didnt do any better on fuel than my dmax:woott:
