Need help with a map

[too many toys]

I have an 07 with a k&n, syn oil, 2 Bros shortys and a pcIII usb. The bike ran fine until I put in the pc. Now it backfires through the pipes on deceleration with the map I downloaded from the website (k&n, 2 Bros exhaust). The bike also seems to run a little rich below 3500 rpm. I dont have the funds or the time for a dyno session right now. Anyone have a map that I can use? Are there any other adjustments I can make? My friend just picked up a 09 zx-14 and hes gunning for me. I dont want to be embarassed.

take a look at some other maps. Try one with less fuel down low. Dont worry about what exhaust the map shows just keep trying them until you get one that works.

do the marble mod, or completely remove the pair valve stuff...the back firing may not be because of the map your running
