    ECU Reflash - Ultra 300X

    Hi,

    I want to Reflash my ECU on the Ultra 300X 2013.

    What is the best choise for Stock Class Racing ?

    I think that R&D and Torx Racing will be a good way...

    I think i have to repitch my Stock Impeller, and i will Need a Fresh Air Filter Kit....

    Does i Need lighter Valve Retainer or Springs ?

    What is Topspeed and rp/mīs ???

    Thanks

    bye

    Which race sanctioning body?

    Most dont increase top speed, there is one that internally removes the speed limited but I think its only available in Australia.

    For stock class go with the R&D R1 tune here

    It's safe for the stock valve train. I highly recommend upgrading to a Riva power filter. Most people use the stock pump impeller with great results.

    With all due respect to Mr. Greenhulk himself, save your $, no intake necessary unless you wanna do all the free air mods you'll be sucking the same hot air in but with a fancy intake

    The R3 R&D reflash with a Solas 14/21 will hit hard from holeshot thru midrange but a higher speed won't be seen, maybe 1/2 mph
