All you need to know for LT1 cars is
www.pcmforless.com. I would opt for buying your own cable from
www.akmcables.com and having the programming emailed to you. If you spend $25 up front, you can have unlimited updates emailed to you if you make any changes to your car. I see that you found out who "the Man" is, but it may be easier for others to find without searching for his website. For the cost of a Hypercrap, you could get the cable, unlimited programming, and maybe even a cheap used laptop to hook up to. Then you could get Freescan (free, of course), or some others that are available out there at a decent cost for diagnostic work.
