i have not used the procom only because of the concerns i have with them, seem to be a hit and miss, then there is the settings and all that, TTP comes right the first time plug and play, as well it can be mounted under the seat away from the heat and crap that builds up under the tank which for me was a great feature, add that to the work the TTP guys have done with these bikes, they know them well enough and i am yet to hear anything negative. When i put mine in (stage 1) it was night and day, reved higher and better, sounded better, idled better, i just really liked it, since sold the bike, but marty has the stage 2 on his and he likes his a good deal as well. i think the price is pretty close between the two as well is it not?
