As the title says, tuned for my 97, from what I've read it's not VIN specific. Takes 5 minutes to install, $75 shipped.

Any specific things it's tuned for, cam, etc?
Or is it for a stock engine? Did it make any diffrence and why are you selling?

I am selling it because I am selling the truck, and put the stock PCM back in before I left for college.

It was tuned for a stock engine, but with these parameters:
-Slighly raised redline
-Firmer/quicker shifts
-Speed limiter removed
-Told him I had an FIPK and dynomax bullet exhaust... not sure what that may change

It made a noticable difference, it was much easier to break the tires loose from a dead stop, and I got 1, maybe 2 mpg. It was tough to keep my foot out of it though, haha. Some guys swear by these tunes, others not so much. Overall I was happy with it.
