That was really confusing. Anyways, I don't see what having an OBDII has to do with what most people (chassis dyno) would measure HP and TRQ with at the wheels. That article is talking about engine dynos right? Engine dyno can only be done if you have completely removed the engine from the chassis of the car. Otherwise, HP and TRQ can only be measured at the wheels on a chassis dyno.

i think the article is talking about chassis dyno. The computer in the OBD II cars adjust performance to the type of driving your doing (ex. slow driving=gas saving, hard driving = higher performance numbers). so your car can vary 10hp on the dyno depending how hard it was driven before you dynoed the car
