So I have a autocal on the way from Kory. I was changing the shifter lever today because the notorious tow button wasn't working. Whole I had the panels off a Banks Ottomind engine calibration module dropped down. All plugged in and whatnot. I had no idea it was there. I have a Banks big head wastegate that the previous owner installed. So now I need to know, can I leave it? Truck won't start without it...
