double check the P/N for the TRE I think you have the one for the 600/750 bikes not the Busa/1K. The P/N for the Busa/1K is JSD-002 not JSD-002a. I don't think it will hurt but you will not get rid of the top end eliminator. just my .02. I just ordered mine today and the 002 is the one that Jeff at JSD told me I needed.

Yes that increase in idle is normal when you pull in the clutch. The 5th Gear map is responsible for this. A micro switch in the Clutch lever signals the ECU to bump up the idle speed. Why? Only God knows why... and a couple of Japanese engineers too. Probably to match RPM on down shift to reduce wheel slide.
