: Jim,

: I see a bunch of theoretical arguments. However I would like to know how you can argue dyno results etc? I have been witness to a certain circumstance in which an individual purchased your OBDII program and witnessed a decent and immediate increase on the dyno. After several weeks the power increase had dropped considerably.

: Now, a few instances in which the power has decreased can be explained away as probability or varied conditions etc.
: But, If these conditions provide variations in measured HP then there would be positive and negative variance by similar % in the dyno results.
: I have never heard of such a result. Have you?

: We can not assume that this "power loss" is a regular and certain phenomenon b/c we do not have a representative test group of the BMW population. However we can suggest a correlation or trend such that OBDII cars lessen in RWHP weeks after flashing OBDII.
