New cold air intake and a Flowmaster 40 series muffler. Sounds like a truck is supposed to. Pretty peppy out of a red light too! Too early to tell if it effected the gas mileage.

Question for all of the experts. After installing said parts, do I need to do a tune to maximize my efforts or will the computer handle it? I'm not really a gearhead!

Thanks in advance,

Elk Country

All you need to know about Democrats is they call American citizens "Deplorables" and illegal immigrants "Dreamers"!
