Has anyone put a power commander 5 from a 08-11 on a newer model. I do notice they have two different part numbers but what is the difference in the units themselves. The newer models do use the smaller O2 sensors, does that have something to do with the change? I have one that was installed on a 09 and I did put it on my 13 and frankly it is four to six mph slower in the eighth mile. I could understand two or three but frankly four to six is a lot of difference. BTW I am using the autotune feature also so the system is using the larger O2 sensors and the vance and hines exhaust does accommodate the larger sensors. Thank you for any information and or help. Best to you all.
