Revainrating 5 out of 5

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
