It is the thermomaster chip and is for speed density 350/autos. Tried it out for one ride, then did a bunch of mods and had a custom chip made. Worked perfect.
I have no need for it and it is just taking up room on the shelf, so make me a reasonable offer and it's yours.

It's the piggyback one, that stock chip connects to. Hypertech part number 122322. I'd like to get $60 + shipping. I paid $80 shipped for it when I got it.

I'd rather have a extra Memcal for my car.
