what you guys think?

I think it's junk. The only thing that could be doing is fooling your ECU into running a richer mixture than it should be; not sure how much power you'd really gain, but their estimates of 15-25 horsepower are optimistic to say the least.

x2 on the Junk.

BMWs are usually rich from the factory so to make it more rich would more than likely just screw yoru ecconomy.

Don't wate your money, save it an buy a good chip instead (such as a MarkD), you will get a better end result.

It definitely looks crap to me. A chip will do a better job w/o screwing up your O2 sensor readings.....

the ECU ignores the Lambda reading at WOT...
