E90 Engine Tune
-
I have been looking at getting a tune for my 2006 325i with the N52. I have found a few options, but most require sending in my ECU to have it done which I can't do being my car is my DD. I have considered the BMS Powerbox, but that is a piggy-back based chip and not a true tune. Does anyone know of any Wisconsin based BMW tuners? Any help is appreciated. Thanks.

Well since no one posted I will post and provide an update to my thread. I ended up going with the BMS Powerbox piggy back "tune". While it realistically only provided like 5-8hp it did fix the awful throttle lag associated with my version of the E90. So far for $278 I am pretty happy.
