Wich is the best to get and will they work on a macintosh??

 

I like Tuner. On a mac? only if you get one without cheese! Actually with VMware and windows 95 running under VMware i hear Tuner runs ok. But IMO i would never try to program with that setup because you have another layer of OS IO for the serial port. If you MUST try it have a spare PCM handy.

 

Tuner will not work on ODB2 cars as far as i know and your 97 is odb2

 

whats the differnce in the programs

 

Basically both do the same thing just different user interface
