Best upgrades for 6.0 liter denali
#1
Looking for the best performance upgrades for my 2001 denali. Its got the 6.0 liter. The only thing i've done is a K&N fipk. I still want to retain drivability.

You started in the right place. Next you could add a catback exhaust, HppIII, and a 160 t-stat. Let us know how far you want to go with it. That would be a start.
