factory pro velocity stacks/Dynoed..

[spamanglenn]

I,d sooner do you a good price on the factory pros.If your going to spend good money on a tune,at least put something on that gives a decent improvement.Shorter stockies will help up top but leave a bit of a torque hole, and still flow like STOCK stacks.Dave was saying torque improvements are realised down as low as 1500rpm on light throttle with these things.Shnitz do a long and short street combo or all shorts for racing as well.You can try my 2 shorts with your shorts,then try these afterwards.Dads is unmapped to suit and he is pretty happy.If a 350kg bike/rider combo can notice a difference,they can,t be half bad. <i></i>
