I recently put a pc3 USB on my bike and downloaded the map for the yoshi bolt on pipes + stock air filter.While the PC3 has GREATLY reduced the backfiring and popping its still there.Is this normal with all aftermarket pipes so should i spend that extra 300 bucks or so for a custom map? Seems to be the worst during gear changes and street riding when the bike is around 5k Rpm or so
