I was able to install this pipe within minutes and test it out. It is LOUD!!! I noticed immediately a gain in power as well even before plugging in the programmer. Love Big Gun products!!

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!!

A: The product is for air fuel mixture, if you have added a exhaust system and upgraded air filter it will allow the fuel injection to accommodate for the added air flow. So if you have added those modifications it will make the atv run better but it is tough to say how much faster it would go.

Q: More power
Over 3 years ago
i have 2014 rmz 250, big mouth intake, Yoshi full exhaust. bike has little to no top end. I kill off the bottom but lose it in straight aways. I seem to have enough power running 14/49 gearing and just looking to add a little more at the top. the area we ride is very flat with little to no real jumps. lot of whoops and long straights. will this product help. even just a little would be good, but a lot would be better.

A: The Big Gun TFI Power Box is designed to optimize the fuel/air ratio of your machine. Depending on the stock machine, it may or may not benefit you with a completely stock motor, airbox and exhaust. Many times with the EFI systems used on the motorcycles and ATVs found today, when adding an exhaust, engine and/or airbox modifications, you will have to retune the stock EFI system to make sure you have the optimum air/fuel ratio. The tuner will not make any PEAK HP gains to your machine, but if your air/fuel ratio is not correct, you can see gains to the power curve of the machine by retuning the EFI correctly to optimize the modifications. Again, the EFI tuners do NOT produce more HP, they allow you to tune your machine to the correct Air/Fuel ratio.
