hey well i recieved my pim today and i was looking at the map sheet.well the one with no spark arr in shows maps up to 10500 rpm. the one with the sparky installed shows up tp 10000 rpm.i call yosh and they said it is the same map as the cb.why couldnt they tell us this before we bought it.oh yeah he also said it will benifit better with the fimak.well ill just stick with my dobeck controller i got it pretty well lined out now.i also added a k&n proflow and i could tell a pretty good diff.sorry i had to vent but i feel like i just got the ole screw with no lube.btw if anybody wants to buy a pim im selling mine for 200 shipped.it is still in the wrapper it came in i got it from cernics.
