the noise that you hear is muffled by the stock muffler. changing that out will cause this noise to become more noticible. the cause of the noise is the computer interrupting the throttle so that the transmission is less likely to be damaged by a bonzai full throttle high hp shift. the noise itself is the pressure from the turbo charger being bypassed from the intake tract to the exhaust. that is the burp that you hear. if you install an aftermarket blow off valve or the mopar "blow off valve" (really just a diverter plate of the pressure to the atmosphere) then the noise will be heard as a whoosh or a sneeze.
quite a number of forum members have installed either the mopar plate or an aftermarket valve. your choice if that is what you want.
am doing the mopar plate next week.
good luck and hope this helps.
