I'm looking at this tuner too for my 14 fatBoy. Also. V&H big Radius and the Ness Air Cleaner. I am worried though that it will void my warranty.

 

Sparky (I keep thinking of Chevy Chase, lol),

It will not void your warranty, don't worry about that.

 

will the bike run hotter because its leaner or will the computer adjust for this

 

I am very pleased with my V&H FP3, the canned tune worked great, but I am letting the Auto Tune feature 'tweak' the tune. Whenever you connect the FP3 and your smartphone it looks for updates so you always have the latest version.

 

I'm very happy and also very impressed with my FuelPak3...
My bike has never run better, and this is after the SEPST and the dealer download, then a set of ViED's...

 

I am going to get the big sucker but I am thinking of getting the cobra fi2000 as the fuel pak always stay the same as the corba is constantly changing if you put a cam in you don't have to change anything it adjusts it self.. It just a plug in and go. The cobra is pricey tho.
