Review on 🚗 Enhance Performance with the DiabloSport Predator 2: 7202 Power Programmer by Corey Ford

Installed on my 2015 Sierra SLT 4x4. Got it out of the box following the update instructions, says you can try without doing the update but luckily I won't risk it. The update took 30 seconds and I went to the truck. The setting matches the photos in the booklet, which is always a good thing. I have a cold air intake on my truck and 275/65/20 M/T and found the tire size fairly easily but never found the cold air option. I used performance option 87 because I think it works best based on other reviews and the website. I will say that before tuning my air intake obviously lagged behind my throttle response because it needed more air than fuel and all the fixes on the internet to remove the minus on the battery and put it back in and the same with the plus on resetting the computer never worked. I'm sure it's the same for most TGE programmers, but this is the one I bought after a lot of research from a beginner hobbyist. I installed it with a full tank of 87 so will update when the tank is dry.
