X2 on that... I have talked with a few people down here in Ca and you could not tell from an emessions stand point, between the stock cam and a 265 cam

On OBDII systems don't they just plug in and talk to the PCM, no treadmilling...............

I think I'm going to order the 265 today. Probably take a couple of weeks to get it in and on the dyno with my schedule lately but I'll be sure to post up the graphs when I'm done.

That's what they do in New Jersey, but different states have different regulations, with California being the most strict.

on the OBDII systems they plug in to the port for RPM, to Read any codes, and see that things are functioning properly during the dyno test. They allso make sure all the moniters are working properly. I.e. O2 sensors status, catylist status, evap Status, and so on...

Thats the same Cam I orderd. If you have not ordered it yet I will tell you were I got mine and what I paid for it...
