Review on 🚗 Enhance Performance with the DiabloSport Predator 2: 7202 Power Programmer by Jason Chaplain

Used on a 2016 GMC Sierra Denali 5.3L engine. I've never had any tuner experience, but when I tell you this thing woke my truck up, I really meant it. These trucks must be configured at the factory. I've used Performance Tune 87 and can't believe its performance. The truck roasts the half throttle tires on launch, the shifts are much smoother (which I didn't think was possible with those clunky 8 gears) and it's just an overall smoother ride. I feel like I have a brand new truck again.
