    How much hp gain on a 5.3 engine can i expect to see with long tube headers, cold air intake, a true dual exhaust and a custom tune by diablo lew

    its really hard to guess man. my old mustang i had i did bbk shortys bbk cai. and tuned it and only got 23hp. dynoed out at 286.4hp 312ft lb tq when they were done. thats with a lil more fuel from my 176lph pump. headers are usually the big difference maker. torque was from 298 ish i think.

    If i had to guess id say rwhp prob 30-45 on a good day. i do know with a nelsons tune and a cam you can push close to 100 hp over a stock application. honestly so far my two biggest " noticable" mods have been my cam and my tune. more so the tune for now tho because my cam needs a stall :)
