Review on πŸš€ Fuel-Efficient and High-Performance Performance Chip/Power Programmer for GMC Sierra 2500 & 3500 6.6L Duramax Turbo Diesel - Enhance MPG, Save on Fuel Costs, Amplify Horsepower & Torque! by Charles Julian

Revainrating 1 out of 5

Not what it's made for.

Did not meet my expectations. Does not meet stated standards. I haven't noticed any increase in mpg or bhp. I wish I had bought something more expensive. Wouldn't recommend it.

Pros
  • Easy installation
Cons
  • Some defects
