flat spot

have an annoying flat spot when accelerating, when you crank the throttle open there is a hesitation before the rocket lives up to its name can be very tricky when you want a quick burst of speed to overtake in traffic, I have had the TPS replaced, have ordered 3 K&Ns and Powermaster to hopefully help overcome this problem, anybody had a similar problem

Thanks idk, have a set of staintune pipes give bike a nice note, under seat K&N filter, no TuneECU or Tuneboy, all work done by bike mechanic not that technically minded myself, the problems only started after I replaced the TPS, have triple K&N's and a powercommader ordered from the U.S. which will be fitted by mechanic and was hopeing at least the powercommander may fix the problem when fitted, the bikes a 2006 classic

took your advice got a cable from lonelec at www.lonelec.com.uk its a good quality one with the FTDI FT 232RC chipset for only $27 AUD delivered with back up support from lonelec if required, there also on ebay uk, now all I have to do is wait for all the bits and peices to arrive from various parts of the world, I had already brought the power commander was only $282 US from Kneedraggers, the K%Ns from Amazon $21 each , no doubt I will be seeking advice when it all gets here.
