Review on ๐ Enhanced Engine Performance: Superchips Flashpaq F5 In-Cab Tuner for 2017 and newer GM Gasoline Engine Trucks by John Gray
The best fuel economy.
Electricity consumption is approximately 1 1/2 miles per gallon. From 13.9mpg to 15.5. Great for 33x12.50x20 with 5.3 v8. I haven't tried the race mode yet. I can't afford super tanks.
Pros
- Grand Prize
Cons
- Annoying
