1st off top notch customer service from vcycle. Got my ecu back today 1st one done with the akra carbon no baffle and i gotta say i love it. went for a quick ride today will do more riding later but so far im very happy. My impressions mirror the others that got their ECUs flashed including those that paid 250 plus. the throttle is smooth the ridiculous engine braking is gone and it feels like a proper bike. I was actually considering selling my bike because the throttle just wasnt fun however not anymore.....636 shock plus akra carbon no baffle plus flash = pure bliss. Thanks to David for giving this service at a reasonable price.
