About GM Tuners when it comes to PCMs? They are only $80 vs. $200+ from anywhere else. It sounds like they do the same things as say DHP but i'd like you're opinions before I do anything.

There pretty good IMHO. I've got them to do a few things with my OBD1/2 hybrid.
They back there work 100%. If you want anything changed, tweeked, etc. they will do it no problem.

Sweet! So they can do the same things as DHP or close to it at least? I suppose I would have to tell them what I want done.

Do they do OBD II?

Jason... you need a better memory.

Darth knows what he'* doing. Very good work.

OH i know he does great work, i've talked with plenty of his customers, and seen references on other sites. I just don't remember them doing much with OBD II

Prescott you need scantool data, and you need to know exactly what you want, and data after the initial chip install.

It doesnt look like they do much with the L36, not yet anyway :?
