I own a`91 2500 Suburban w/4L80E that I`m installing 35"tires on.I haven`t found anyone that makes a VSSBuffer for this vehicle.Superlift`s Tru-Speed starts w/`92 body.They suggested getting Chip burned.It`s that,or have custom harness made-up like when installing 4L80E in classics/hot rods.Anyone know of a company that makes a Buffer for this model?Has anyone else worked this out before?I know I could always lower gearing to compensate,don`t really want to get into that now.

E-mail me offline, I have a doc on modifying the VSS DIP switches. You're on your own if you trash it, tho. ;)

Got it from the GMECM mailing list http://www.diy-efi.org or somesuch.

It's for when I swap my 91 4L80E into my MH.
