i am looking for sugestions on what fuel tuner would
be best suited for my bike, 2007 jackpot 100ci open
loop system,rpw slash pipes,s&s intake. also do i need
to take it to a dealer and have it put back to stock setting
or is it just plug and play?
you will see alot of opinions on this topic. The lloydz VFC (made by Dobeck) is a great option and their is the Power commander 5 as well. Also a great option with more adjustments/refinement. Out of the box for the money I like the Llodyz VFC (from $150 under the Wiseco brand - to $300 with Llodz special touches). Dobeck makes the product for a lot of brands - see link http://www.electronicjetkit.com/EFI-controllers.asp
their are TONS of examples of likes and dislikes. The best are auto tune options with Dobeck and PCV but they are the most expensive (2x as much).
