Gears difference for towing chip?
Does/should it make a difference which gears I have in my truck for the towing program? I have the 3.73 LS gears in my truck rather than the 4.30s, so I was wondering if the shift point changes programmed into the Diablo were tuned for one or the other. I'm sure I didn't specify this info, and wasn't asked, so I wanted to make sure I have the right program.

If you put the item into the cart without clicking details it would not ask you to provide vehicle details. If you do it via the details link it will.
The V10 cannot have its speedo calibrated but the shift points can be changed. This requires custom programming and there is a fee for it. Give us a call or check out the custom sheet at: www.motorhaven.com/custom.htm

I ordered it via the details link and provided my truck info, but I don't remember telling which gears. I haven't changed gears. I just wanted to make sure that the shift point changes in the towing program I got wasn't designed for 4.30 gears when I have 3.73s. The program is HMT1TWSHF-4BANK. I can't really tell any difference between the regular performance setting and the towing program (either empty or pulling my 10K# TT), so I thought I'd ask. I can tell a slight difference between stock (off) and the two performance settings when towing, and a BIG difference when not towing, so the chip is working - no positive change in MPGs whatsoever though (maybe a little worse). 
I'm going to give it few tanks and reserve judgement on the MPGs until I get a better "normal driving" test rather than the "what will it do" kind of tests it's been getting so far.
