Now I have not yet contacted Brocks about this issue. Fact is maybe I don't have an issue at alll. Just curious if anyone else has experienced the same thing. I installed a full street smart exhaust. I think it's also called a gen 3? I bought my pc5 from brocks with the street map pre uploaded to the pc. Followed instructions to a tee. Everything fit beautiful. Bike started up easier than usual. Runs like a demon. Odd thing is it has a "lumpy" idle. It doesn't fluctuate or stall or anything. It does smooth some after bike is fully warmed up. Sounds like I installed a larger lift cam in the bike. Runs great just seems odd a FI engine would idle this way. I was just curious what others had experienced. I have gone back and rechecked my work with the Pc install and to make sure I hadn't pinched any line, etc. Bike is a 2011 with approximately 5k miles.
