[Mr.G20 M340]

I just flashed my car and they had to put it on the new DME software and the burbles and pops are totally gone.
I went with mission performance and I asked them to make it pop and they said the new update prevents the car from popping. I don't know how true this is, I'm waiting to see if I can find someone with BM3 and newest update to see if that is true. Alex at mission said I can send him and email and they'll see what they can do but they don't like to do it because they want to save the turbo. The thing about that is the burbles and pops were significantly louder and more noticeable when the car was stock and old DME so I'd think bmw would have tuned the engine to not deteriorate the turbo with the stock burbles it has. I know it sounds like I'm a deuce for saying this, but the car doesn't feel the same when I let off the throttle at high speeds after shifting up and If I see BM3 has a way around this then I'm going with them. I'll keep you guys updated
