Shark Injector - Performance Improvement

[GAM]

I just wanted to make a comment about this performance improver. It doesn't add a whole lot to a 2001 525i. I used a performance chip on my 1993 525i and it was worth every penny. For the 2001 it only provided very minor performance gains. So before you spend your money think hard about this performance mod for this year/model of car.

If we sticky this post, I can refer to it in 20 years when I can afford the 2001, if I don't already have my e28 :D

What engine in the 2001? M52??

Yup, there isn't much power to gain in most BMW OBDII cars, except the turbo variety. The software upgrades do help, but with other modifications working in conjunction. Thanks for letting us know so we don't waste out money.
