i have just fitted a stage 1 SE air filter and a set of big shots and SE tuner to my 2016 wide gluide and when i back  off  i get a lot of popping thought the exhaust any tips how to stop this thanks

Have you got any baffles fitted weasel?

I have loud baffles fitted and only get popping on desceleration

yes they are standard baffles that come with the pipes

Pipes not done up properly or it's out of tune, best first guesses

Get it tuned properly by a professional not by just downloading a map

Open up your map and make some changes to it in 20kpa A/F table, ride and fine tune it from there

thanks for that made changes in 20kpa a/f table and now popping gone thanks again

yeah its very easy stuff, these are just efi internal combustion engines, and very basic at that

well done
