Try to remember to do a TB reset before you take off on the trip back, and just try to wipe the grin off your face.
LOL....yeah...I wasn't going to say anything, but the car apparently put down astounding numbers with very little mods (NW CAI, Code 3, resonator delete) and that tune. Something like 355/348.
Maybe I could use the 91 octane and then use some of the actual octane boosters (not the fake walmart ones). If it actually becomes a problem.
