2000 silverado performance questions
#23
TUNE! i did a custom tune on my stock 5.3 2000 sierra. i may have only picked up 10whp peak, but its a completely different truck. stock tune is extremely lazy, slow weak shifts, no downshift to 2nd from 70mph (which results in the truck barely even accelerating)
i have HPtuners.

Electric fans help power and mpg, and give you a ton more room for an intake.
