Downshift Backfire!! after chip mod....

A friend of mine works at a European chip chuning branch.

He gave me a call lastnight....he just received the "motorsport' engine program for my E92 M3.

Now the car backfires on downshifts!!

Fuck! You can really hear explosions in the airbox.!
I have to check the airfilter...maybe it blew off?

Actually i think it's cool!

Anybody else have the same?
