a Lund or aftermarket tune that isn't going to ruin my motor? Car is a stock PP car, 91 oct, I wouldn't mind a cammed tune as well. Are the cammed tunes still ruining converters? I don't expect to have mine on much longer and I don't drive the car daily or anything. I already have an X4. I Also want a tuner that isn't going to charge me again everytime I need the tune changed for mods.
