after installed cause crazy backfires when shifting to lower gear(1-3). Anyone know how to tune the ecu to reduce that crazy backfires?

This is why I'm going the David Platt route I noticed on a few of the bug bike videos they had backfire and flames didn't seem to be running right without tuning
 
yes, I checked the bug instruction & they claimed need to tune but my local dealer refused to tune for me. The bug exhaust is pervious owner installed & he think the crazy backfires is very nice but that's too much for me & also generate extra heat
