Jim - 2009 Kawasaki ZX-14 - Naples, Florida

BEST $50.00 EVER SPENT PERIOD. i have a 2009 zx 14 after running a pc v with the dynojet map i was not impressed it ran real rich and had jumpy powerbands after seing a post on a zx forum and the 6 page thread with all good comments i had to try i emailed jeffo and got a response within hours sent him the money late night and the map was in my email the next morning called jeffo for help with the install and he walked me through it step by step the bike runs great no more jumpy powerband all smooth in all gears at all rpms no more rich condition and no more black smoke !!! FYI local shops in my area charge $275 plus for a map that doesnt come close to jeffo's thanks man!!!
