Do any of you guys with Hemi's have any opinions/experience with the Hypertech programmer? I'm thinking about it, but not sure if its worth it.

 

In addition, are there any other companies that make programmers? Is there anything where I can program the chip myself on my laptop more specific than the generic MAPs? I am familar with tunning in small block chevy's, just I'm getting a Ram and looking ahead for when I swap the cams and heads.
