hotcam tuning ??
 

just finished my hotcam install, just wondering what exactly they tune when i send the pcm out, because the car runs pretty good now, what changes will they make to the pcm for the hotcam?

Not sure. That kind of question should be asked to the person or company that is doing the tuneing. They will be able to tell you exactly what they do. Probably tune the air/fuel as well as the timeing.

And up the rev. limiter depending on there it's set stock.
