Are you doing it yourself or the stealer? I did the pipes and A/C myself and took it to a Indy for the carb jet and a dyno tune.The 07 are the first sporty with EFI. Sounds like Dallas is write he has the same year model as yours.
On another note, I have talked to several people and read several posts about the 07's OBDII PCM doing a relearn once you help it breathe better. I have 3600 miles on my bike now and just opened the pipes. When I first did the pipe mods it would almost die and backfire often on a compression gear down slow down. Now it rarely pops and mostly when it is cold. The negative part of it is, the programming will compensate only within a certain range and still needs the new programming.
