I just had V&H big shot staggered pipes, a heavy breather, and SE255 cams added to my 2007 Heritage. The dealership that installed dynoed the bike and I picked it up yesterday. Everything sounds great and the performance is much better than stock, but the bike not has a loud decel pop when downshifting. Is this normal or should the dealership remap the bike again? What causes the decel popping? Thanks.
