I've tuned a couple of Duramaxes and an owner of one (co-worker) informed me that I won't be seeing him very much in about 2 weeks (notice), so I'd like to get him a switchable tune. His tune is too hot right now for towing.

I know...I'm sure there's SOME code on there we don't need though. I don't need the E85 tables, or the manual tranny stuff...

But some people who *have* E85 with the same OS do...
You can blame GM for being too "conservative" with the calibration space. LOL
