how much does everyone think a transgo JR and i 1057/1058 hold in an 07 6speed Alli? im thinking of trying my hand at tuning my dads LBZ after he gets his trango JR installed (the converter will be a early B-Day present for him). i would like to try it as well so i can get used to the newer style ECM but i dont want to limp a truck that isnt mine. the truck has cognito UCA leveling kit with 285/70/17 tires, MBRP cat-back duals without muffler. thanks in advance.
