Is it necessary to have a power commander installed with an aftermarket slip on exhaust? will it harm the bike if i dont have one installed?
power commanders are soooo old school....
most bikes newer than 2007 can have there existing onboard ECU reflashed..(upgraded)..then dyno
for alot less
If the bike is running well and there is no loss of power in your rpm range, then you don't need a PC...
I have one installed with my akra slip on because I had to remove the cat and it still backfires every once in a while.
Don't get me wrong, I don't regret buying the PC at all... Never bothered changing the map because I'm pretty happy with the way the bike runs now...
BTW... my rearsets should be in tomorrow lol... you free this weekend bro?
