Deceleration popping

I've noticed some deceleration popping on shifting from 1-2, 2-3. I've got a stage one upgrade with a dyno. It's not bad but, I was wondering if thats normal ?

If it just started, you could have a leak, but if it has been happening since the dyno then it is not properly tuned

Aren't you speaking "acceleration" (1-2) (2-3)... I think you got it backwards?

Actually he doesn't. When you are shifting gears you decelerate. If the bike has a tuner installed the deceleration table is what helps control popping during shifting

If you paid someone to dyno tune it, take it back. (or take it to some that knows what they are doing)
It should not pop when shifting up or down.

A Thundermax tuner would be a better solution. Mine never pops, even on a had decel.
