New hear so cut me a little slack as Im learning.
2013 850 XP

Im putting a snorkel your atv snorkel kit and a big gun exhaust on this weekend. Buddy of mine encouraged the TFI by big gun also. wondering if this is a must have with these mods?

A snorkel will usually change the amount of air coming into the air box, along with a high flow filter and an exhaust you will need a programmer. The Big gun TFI is made by Dobeck and marked up considerably. I carry the Dobecks, and the EJK 3.5 at $235 shipped which comes preprogrammed for your machine and has the ability to not only add but subtract fuel unlike the previous versions that are less expensive. Believe it or not you actually need to remove a little fuel in them at certain spots.
