but that is a reg TB verter...out of a 4.2L model...5.3 and TBSS verters wont be any diff than our current verters....flashes to 2500, brake stall to 26-2700. Bolts right up, no need for retune or anything. One I got came out of an 04, supposed to be the loosest out of 02-whatev yr they stopped making them.
Not everyone wants or needs a big stall. For a dd I want a small stall. 3200 Max. Circle d is about $400. Mexiflip paid like $50 for the converter. Better overall than stock. Won't kill mpg. And his cam is on the small side so no need for a big stall.
