im looking to buy a micron slip-on and a powercommander for my 06 f4i. my question is, on the PC web site, they have maps listed for an 06, and an 06 california. i know all 06 have the o2 sensor. but which map should i get? is there a diff bewteen a 06 and cali 06? thanks, dan

 

uhh so anyone??? haha or i could just eliminate the 02 sensor all together? would that really affect anything besides gas mileage???

 

You have to buy the middle pipe calif. model so you can fit the O2 sensor, and yes your motor was thought to use the sensor.

 

you could try both of them to see which one works better, it's not going to hurt your bike ether way. i also have a map i could email you that a guy sent me that i run in my f4i that kicks ***.
