I recently installed Vance and Hines "big radius" exhaust and a Roland Sands air cleaner to my bike! Need thoughts on a race tuner, power commander, or fuel pack. I have heard that the bike will run too lean and possibly damage the motor! Any suggestions?

 

<sigh> mythology abounds. It will not damage the motor, the ECM will adjust to both. (prepare for people to claim it wont, but it will)

However, it will still run EPA lean, and hot.

Personally I like the Power Vision, get it from Jamie at Fuel Moto and he'll put a map on it for your combo and it will be pretty darn close.

But questions like "Which tuner should I use?" inevitably yields a list of every tuner on the market.

Love these topics.

 

I disagree with Keith that ECM will adjust, but agree with the rest of what Keith said. I like the PCV. Jaime mapped it for me. I agree you are going to get every answer though on which is best.
