RaceChip Ultimate: safety and warranty

Our optimisation software ensures that the RaceChip works only within your engine’s safe rev range. Thanks ,to our Engine Protect System, when you get close to the red line or go into the red, the chip automatically shuts down so that your engine is running in stock condition again. As soon as the revs drop, the chip turns on again. With RaceChip Ultimate you will receive a 5 years warranty.

I was blown away by the power gains I experienced after installing the DrakeBox Monza on my Honda. The acceleration and top speed improvements are noticeable, and the Monza's ability to reduce fuel consumption is a bonus. I'm extremely satisfied with my purchase.
