Review on 🚀 JET 76100 Powr-Flo Throttle Body Enhancer by Justin Trujillo

Seems to work fine with my 03 Yukon XL 5.3L. Throttle response seems a little better, and it seems like torque could be a little better from standstill to low revs. There is no check engine display. No fake mode. No instructions. Note: Before starting the vehicle, make sure you turn off the throttle. (Turn the key to the ON/acc position, but do not start, fully press the pedal and release it several times, then start the car.)
