quick thoughts: i want to put a Jardine slipon on my f4i but a power commander is recommended. i heard people burn plugs if they dont use one. Thoughts? I really dont have the 300+ for the power commander so I'm wondering if it's worth it....Thanks!!!!

 

I have done a 02& a 03 i have never fouled any plugs but the PC111 is defietly worth the $300 !!. Go ahead and get it tuned as well. you will be looking at 5 to 8 HP & 4 or 5 pounds of torque. *#@@ YEAH!!

 

Your bike will run without it, but it will run better with it besides the added HP and torque it will make since it is running better
