Finally got to ride my glide after new dresser duals heavy breather and pcv,it backfires/pops intermittently when shifting or downshifting at a higher rpm,could it be the map or an exhaust leak?

 

check for leaks first, rule that out

I talked to Keith at Fuel Moto because mine popped every once and a looooooong while and he said that with my Power Vision, it is running closed loop, so the ECM will slightly adjust. I rode today for like 60 miles and it did it one time at the beginning of the ride....
