    2013 RXP-X 260 mods, VTECH what to expect for MPH

    Decided to go with a VTECH tune for my bone stock 2013 RXP-X 260. What should I expect for MPH? Also any other supporting mods I should consider that are good gain for the price.

    What tune you going to start with?

    8375 you can keep the stock valve train intact. I'd probably also throw on the 4" air intake. You should see a good 72MPH GPS(maybe 73 under the right conditions) if your RPMs on that tune are hitting about 8250-8300.

    Popular set up is 8375 tune, Fizzle intercooler upgrade, 4" air intake, stock prop pitch or SZR 15/20 pitched properly, RRFPR, and free mods. Depending on where you ride that set up tuned in should get you in that 74MPH GPS (+1/-1 and no lower then 72MPH) and be very reliable.

    In the cooler months I was seeing 76 on a quarter tank, but now in the summer heat it has dropped to a max of 73-74 in same conditions. The new intercooler has really helped with heat fade.
