i ask becouse ive got a 05 crew, 4.10's with an auburn, long tubes, magnaflow, ngk's, msd wires, k&n cold air, trango shift kit, and a small cam
210 218 530ish, but the truck is an absolute dog up to 3k rpm. nelson tune did make it pull harder but still no bottom end. wont spin a tire. truck gets beat by stock 6.0 trucks with drive by cable and a 5.3 dbc is right on my arse! i should have 60-70 horses more than these stock trucks but the pound me on the takeoff. every cable operated throttle body ive driven has more takeoff than me. drove a stock 5.3 4wd today with 3.42's and its worse than mine, of course it should be its stock. but my point being, cable trucks seem peppier, and faster off the line than a drive by wire truck. comments anyone?.....gene
