What can i do about my tune?
Hey guys, my car has a PCM for less tune, and the guy i got it from said that they fattened up the AFR more than it should be, so it'll affect gas mileage. I'm wanting to get it re-tuned for better gas mileage as it is a daily driver, how should i go about it? Should i get a hold of PCM for less? Can i get something and do it myself? I don't know much about tuning. Here's my list of mods for reference: automatic trans, mods are: moroso cold air intake, trick flow intake elbow, 160* t-stat, e-fans, 52mm holley throttle body, injectors, 1.6 roller rockers, ported and polished heads, screw in studs and guide plates, off road y-pipe, full 3" exhaust into a dumped bullet, UMI panhard bar, UMI lower control arms, edelbrock torque arm, UMI tri-point subframe connectors, aluminum driveshaft, 3.42 gears, ARP head bolts, drilled and slotted front rotors. PCM for less tune.
