Easy to Install

The TFI Power Box was incredibly easy to install, and only took a few minutes for it to program itself to the exhaust. I can feel and hear the performance changes it has made and couldn’t be happier.

2011 Raptor 700R

This is a great fuel system. Pretty easy instructions. I have this on my raptor and the pro design pro flow intake and it absolutely flys. I will soon be getting the big gun exhaust for it. This makes my quad a lot more snappier and run a lot better. Great product!!

Question answered Over 5 months ago
Answer: Although it boasts plug and play, and that it does come with some maps already built in, you will still need to tune it for your bike, and conditions for best results. You will need to purchase an AUTO-TUNE feature separately to achieve what you are referring to.
