Do I need a Gryphon - What tunes are included?

[66gtk]

Thanks for your help - Regarding the current state of tune. If it does have a non-stock tune installed, Do the custom tunes work on the premise we are starting with a stock tune? If so, how do I return my vehicle to factory stock before I start messing with things?

When I purchased my truck, it had 40K miles, and almost new looking factory tires/rims. Makes me think the PO put on aftermarkets, adjusted the speedo accordingly, and returned to stock wheels/tires when the lease was up???

I think you've got it! Or, the PO never adjusted anything - some people don't. Bill didn't say, but from other posts, I gather he has a way to make the Gryphon play with your PCM even if there IS a custom tune already in it.

Yes, though, the Gryphon's tunes start with the premise that the PCM has a stock tune installed.

Here's the scoop on modified vs. stock...

The Gryphon will detect if the PCM is stock or not, and if it is NOT stock then it will stop dead in it's tracks with a checksum failure and we'll need to be involved to restore the PCM back to stock. It's not a big deal to do and usually only takes a few minutes.

Take care.

Is that cool, or what?
