1HD bikes do not have the active air and exhaust
5HD bikes are "international" models and do have active air and exhaust
In my experience , only TTS and original up to 2008 Screamin' eagle race tuners switch off the active air and exhaust, using a specific calibration to do so.
Maybe power Vision can , but I don't use those.
Supertuner pro I have never switched off AKA "disabled" active air and exhaust.
It will be the true duals that are causing the decel popping , seen that many times before now.
can be "tuned away" or minimised
PM me an email address and I'll send you a calibration that may help with the decel popping
No worries.
I've used that calibration on a few bikes with true dual systems
Personally I prefer an exhaust system with a crossover/power chamber/ link pipe , call it what you want.
BUT guys have got what they've bought and you try to suit
Glad it worked , has done most every time for me.
