Hi fellas,*

I recently installed TW 222 cams in my 2011 FLTRX 103.*I loaded the map *and all was well. I ran auto tune and was able to get to the (-1%) - (-3%) with 144 cells tuned. All was well until I installed a decatted head pipe. Now the closest I can get in auto tune is (0%) - *(-11%) with 179 cells tuned.... Is this because of O2 cross talk I have read so much about? Any input is appreciated as I'm about ready to reinstall my catted head pipe so I can get it tuned correctly with PV.

Thanks for any input!

 

Cross talk is the exact reason I took off my decatted stock headpipe and put V&H Power Duals on my Limited and Dresser Dual headpipes on my Road King. Those O2 sensors just can not properly separate the oxygen signals side by side properly when that cat is removed. Since my Power Duals are more like the stock 2-1-2, V&H moved the rear sensor up the rear pipe much closer to the head to deal with the cross talk issue and get a better tune.
