Review on Pedal Commander - PC77 for GMC Sierra (2019) (4th Gen) 1500, 2500HD, 3500HD, SLE, SLT, Denali, Elevation, AT4 (2.7L 4.3L 5.3L 6.2L) Gas Engine Throttle Response Controller by Brian Samuel

Revainrating 4 out of 5

This gives you an instant boost! Be extremely careful in Sports Plus mode!

Pedal Commander makes the throttle response much faster than factory. He doesn't. The upper speed limiter is not deactivated. It doesn't increase your horsepower. Not sure if the rev limiter disables it or not. If you're looking for something that gives you faster response times when you're accelerating, this is definitely it. This made my 6.2 on 420 hp get up and go without hesitation.

Pros
  • GAS ECONOMY: ECO Pedal Commander mode can help increase your GMC Sierra's fuel economy and save up to 20% fuel.
Cons
  • Some small things
