Damn thanks Jason that was a big help! I gutted my cats this morning took a total of 2 hours start to finish. I spoke with the tuner and he said I shouldn't be WAY out of whack but "we can definitely squeeze more power out of it with what you've done" he wants 190.00 to retune it... Should I do it after I throw the magnaflow on? Man I hope someone comes out with an LSD for my truck
