Anyway, I would like to get rid of the popping and get the bike running a little richer therefore cooler. But...I don't want to give up much in the way of gas mileage. What will happen to my mileage is I put the fuelpak on using the recommended MAP for my setup?

Hi JPB.

Ok, The best time to due a SERT is in the winter, as cold air has more oxygen, that can cause a lean run when cold if you set the curve on a hot day.
But that is not what the stage 1 download is, it is a factory EPA approved fuel curve that may help the bike run right......yours would be the first I know that did.
It's the EPA fault, they want ever tighter standards.

Anywho, yes, the fuel pak can be used to help the curve get dialed in far better.

As too backfiring, a low restriction exhaust will encourage it, mine dose it from time to time, one pop on first to second shift, every ones in a great wile.
On decell, i get the gurgling type sound, but my Pro pipe is a really open pipe, it would be quite difficult to make it totally quite, and perform as well as it does.

With that said, will the Fuelpak help your bike?
Yes, it will help it accelerate better, run smoother and cooler with less backfiring, will it eliminate it completely 100%?
No, but neither will anyone else's, even the Harley SERT warns about that, it's the exhaust design.

It will run better then it does now, and it is worth the investment to put it on.
