i am thinking to install the procede or cobb on my 07 335i, but i am a little worried that i would blow the turbo.... one of my friends blew his turbo on his 08 335i with cobb!!! does anyone here hear anything like that? from my friend word, his turbo is making very loud sound after installed cobb and driving for like a year, he doesnt have any other mods and he was not hitting it hard, but after he restored back to the stock setting, the sound went away.... is that a turbo failure? and i see the procede has a higher boost psi, so does anyone here have a procede install? any problems? i am not planning on doing too much engine mod, just the ecu, and exhaust, what do you guys think?
