I recently got my 2014 SGS dyno with a power vision tune, however, I have been noticing exhaust pops. Curious is this normal? I have a stock modified exhaust, Andrews 57H cams, SE breather kit, decatted headers...

 

Not normal in my modest experience. Give your dyno shop a call and discuss it with them.

 

With changes (in air flow) as you've described, popping is common. But that should be have addressed by the person doing the tuning during the bike's time on the dyno.

 

No It is NOT normal..You paid good money to have it tuned bring it back and make them fix it. The bike is probally lean in the decell area.

 

Check for exhaust leaks.

 

Should have been addressed during the dyno for sure

 

+1...

It's either an exhaust leak or the tune....

If you cannot find a leak, have your tuner fix his tune...

 

The tune was performed by Valley Racing out of Beecher, Illinois... I will have to give them a call but yes this should of been addressed prior to releasing the bike...

 

I would really question the quality of the individual doing the dyno tune.

Make him fix it, and then find a guy that knows what he's doing.

 

Ya got a problem with your dyno guy. Low numbers and popping do not a good tune make.
