Grove Rat wants to know Dino or Syn?
2005 Road King Stage 1

This is the Chart from my new to me 2005 Road King stock 88" TC. One of the PO installed V&H 4" Slip Ons and I removed the "Y" pipe and added the FullSac True Duals and a V&H VO2 AC.
I took the bike to the dyno guy and he checked the ECM and it was stock so I was glad it was unlocked. He used a Power Commander tuner and set it up on the dyno.

The Red lines represent the Baseline with 55.2 WHP and 82.6 FT.

The Blue lines represent the new tune with 73.7 WHP and 86.8 FT.

I am pleased with the difference in peak performance but I especially like the duration over a longer RPM range. I haven't had a chance to really stretch her legs yet but before the new tune she noticeably started to fall flat around 95 MPH. The ride home was in town dealing with traffic so no good runs but it was much more responsive when I was able to roll on the throttle a little.
