Yes, you should get an ECM download or add on a tuner or fuel manager. Running a more open air cleaner and mufflers will lean your bike out more than it already was. When you say SE air filter, I assume you mean the entire air cleaner assembly to the SE Stage 1. If you only changed the filter itself, you are probably okay.

 

Ditto

 

You need a tuner with the 80293-99 slip on's & A/C... The download for 07 isnt enough.. It's for the new EPA style mufflers, and the 06 download is for the 88.. It'll run and act ok but it's too way to lean...

 

thanks for help
