Easy installation. Matched with Vance Hine big radius exhaust and used map for this combo. No further adjustments needed bike runs and sounds great couldn't be happier with this product and Dennis Kirk . Always by my bike parts from them best prices and fast delivery.
Fuel Pak works great. Plug and play, no expensive Dyno to program. I have it plugged in with the V & H Big Radius exhaust and THunder Air Kit. Nice horspower gain and it reduced the backfiring of the exhaust when used withour the Fuel Pak
The Vance and Hines fuel pack added to my 08 Yamaha 1900 handles the altitude in Denver and the performance on the run to Sturgis was without issue. The acceleration is smooth, strong and without issue. The support from Vance to correct a minor adjustment was spot on and performance is great.
Easy installation but the black and white pics are a little hard to make out on the instructions. I bought this one because I installed the V&H Pro-Pipe on my 2007 Warrior 1700 and didn't want the bike to run lean. Very easy to program the settings and I like that it give me the settings if I install an different air intake in the future which I am planning to do. V&H also gives you a support number to call if you needed to make any further adjustments. Why mess around with the other type modules and have to use a computer and then download the settings? I like EZ.
The FuelPak made all the difference when coupled with my K&N air filter an Vance & Hines Cruzzer exhausts. Definite increase in power. Too soon to judge fuel mileage effect. The plastic cover to the control module had a slight crack. Nothing serious, but the reason for the "4" on Fit/Finish.
Make sure before you buy that you can get the mapping for your particualr bike and its addons. If they do not have and you request, the return email consists of try the stock bike settings because they have not tested on your setup. Besides that easy install. I backfire a bit but probably because it runs a little too fat.
This product was priced right fit well and installed fairly easy but i was disappointed with the performance on my VTX1800C . I spent more time on the phone with the tech line than I did riding . Never got top performance with this product it didn't wrok well for me , so good luck !
