Can someone tell me the difference between the 93 performance and the 93 towing tune....besides the obvious. I have installed both and can't tell any difference between the two. I would think the tow program either moves the power band lower in the rpms or it has a less aggressive timing advance than the performance setting but more than the 87 tune? Any ideas?

I'm not to sure, but I've got the book that came with mine if you don't have yours. It might have something in there that specifies each program.

I think the towing holds the shifts longer.
