not all stuff, the chips are different. I found out that 2000, 2001, 2002 are different. My truck is a 2001 Crew cab with a 2002 computer. So Be sure to check before you order. And as listed with the previous post, I was dealing with Jet. Hope this helps some. B&M shift improver will not work on my truck. It's only good through 2000 models. April is the expected date from what I've heard for that. Hypertech programer for 2001 part number is 30008. This I read from another post, another site from a guy who called Hypertech. It's not listed on there web site, but he called and got it.
Good luck
