While all of this could have been remedied with a tune, I also didn't love the sound. For me personally, it was a better move to sell the drummer and buy a stock can (which I prefer the sound of) and make some cash than to spend several hundred dollars on a race ecm or countless hours data logging and tuning myself. Why spend two track days worth of money to fix a problem when I can fix it a different way and make a track day's worth of money?
And yes, it also popped really loud on decel. That was one side effect of the drummer that didn't bother me.
