C90 popping & backfiring

Help please...I have recently installed Hard Krome 2.5 strippers and a power commander on my C90 (stock air). Unfortunately, the bike likes to pop / backfire on deceleration. I have tried a few different P.C. maps from their website, but no fix yet. Can anyone help and supply a map that might help this configuration??
 
The popping is cool :bluethum:

I had same type of deal with my bike, the popping is unburnt fuel in your exhaust, this is normal. The reason you didn't hear it as much before is because your stock exhaust does a fantastic job of dampening popping and backfiring noises. Are u using the recommended map for stock intake?

There are a ew things you can try
: Plug your pair valve.
:Try playing around with different fuel grades. I get more popping with hight grade over low grade.
 
Email me. I have a map that will fix backfiring due to aftermarket pipes. If you still have popping after installing this map, check your exhaust for leaks, and remove/disable your pair valve.

Give me as many details as you can in the email.
