Hey guys and gals. I have my 08 kfx450r with a single stage genisis chip with fmf slip on and uni filter. Lots of cosmetics that made her loose some weight but it still isn't fast enough. Yesterday I raced a YFZ450 and I lost. Not too happy about this. I'm just lookin for some small hints on how to go faster bottom and top end and not spend too much.

First thing you'll need to do is ditch the stock intake..at the very least do a search here for theduv, he built his own using a ltr tube...and you'll need a pciii to tune it...can also change the gearing to a 15 up front but i'd probably wait till you change take care of the intake & pciii first...that'll get you decent power.

What does a pc3 do that any other efi programmer doesn't ? I'm asking because I don't understand the price difference between them and all the others . I've several mods along with a cheap dynatek efi that still will provide %20 more fuel and that's more than pleanty to run rich .
