Some interesting posts here:
From what I read in the first thread, does decreasing the fuel in the throttle-on position, improve decel popping? It seemed that both options: increasing throttle-off fuel or decreasing throttle-on fuel would help.
(For those unfamiliar, PowrPro has two modes: cruise and acceleration. The unit knows whether the throttle is off or on based on a built-in accelerometer.)
I'm happy with the cruise setting of the PowrPro because it's stabilizing my idle. The PowrPro by default is adding fuel to my acceleration which I don't think I need - I'm quite happy with the performance of the bike the way it was before the PowrPro - and I think there was less decel popping before.
I'll play with settings once I get back from my trip. I'm just curious about the theory while I'm traveling and can't test anything out....
