2015 Silverado tuned pull 

IV ORIGiN not really sure man. I had it tuned at a performance shop

Stock 5.3? Probs no more than 6200-6250. Any more and you’d simply be reving tf out for no reason without additional airflow for needed hp

I think in this video I was running the carven R series also have long tube headers and no catalytic converters or resonator.

@@chasec4478 man that thing sounds good!

Ppv Murica thanks. Anytime you start bolting on aftermarket performance parts it’s always good to get it re tuned. Most performance shops can do them or you can order a diablo tuner.

Thanks for responding. I'll just wait for my kNn mit comes in then I'll just tune it with all in one go. I have the venom 250 muffler on it sounds tight

Ppv Murica nice! Sounds like a good set up as well. Once you tune that truck it’ll be like a new vehicle

Even at cruising speeds did torque and stuff like that improve with the tune..?

Ppv Murica oh yea it’s a different truck from what it was. I still need to retune it since I put 22’s on it.
