Review on Qzucar Device Disablement for Active Management by Edwin White

Revainrating 5 out of 5

Works perfectly! for spare parts

I drove around the city for 4 days and the car never left V8 mode! Throttle response is better and clunky shifting and low speeds are gone too! Worth the money for peace of mind. I've done lifters before. 2007 Sierra New body with 153,000 miles. Gas mileage hasn't changed, but hey, you don't buy these trucks to save on gas.

Pros
  • Very good price
Cons
  • Negative impression
