    Rxtx 260 and Les Cooke reflash

    Just wondering how many RXTX 260 owners have had there ecu done by Les Cooke, love to hear some results. Im sick of seeing the RPM pull back to that dam 8040 rpm, to make it worse I got smoked yesterday by my old ski (255 tx ) It has 15/22r R&D grate and air filter mod, it didnt just beat me it pulled away like a train

    I dont have a 260 but on my p-x it made a world of difference! Seemed to have alot more midrange power and sounded so much more crisp in the topend! Picked up approx 200rpm.

    Les have some different maps for 2010RXTX. If you looking for the stock - reflash for 8450rpm and change retainers. Working exelent. After impeller repitching give app74-75miles/h.

    Wait a little bit on the reflash. I heard something interesting. Hopefully the info will be released soon! Might be worth the wait
