What exactly is a gryphon upgrade.

So what exactly is a gryphon upgrade? Currently I'm a computer programmer, and have in the past was a chip based programmer, so that is why the curiosity.

I mean is it a new chip with your custom code, or do you just reflash the existing chip in the programmer with your code? I know some of it may be sensitive so a simple yes or no will do if you can't fully explain.

Now I have a stock evo. The only performance mod I've done right now is the Gotts mod with plans to add efans, underdrive pulleys, exhaust and others as time come. Is it worth it to wait for all that to be done or should I change the evo to the gryphon before hand?

I normally run 89, and and plan on doing some towing down the road, I was thinking 89 performance, and 93 tow tunes, what are your thoughts?
