Review on ⚡️ Innovative Fuel-Saving Performance Chip/Power Programmer for BMW M6 3.5L, 4.4L, and 5.0L - Enhance Fuel Efficiency, Save on Gas & Boost MPG, Amplify Horsepower & Torque! by Dan Sturm
Great buy for the price!
Huge difference to my 2008 BMW M6. Changed the rev limiter and increased the power enough to feel it. Highly recommended for the price! I also had a setup question and emailed support and they responded within an hour!
Pros
- Engines and engine parts
Cons
- Hard to tell
