Cheap speedometer recalibration?

[ajzcamaro]

I searched but couldn't find what I needed. I have a 1997 Pontiac Firebird 3.8L 5 speed that originally had an open diff, drum rear wih 3.23 gearing. I just swapped in a Y87 rear end with LSD, disc brakes, and 3.42's gears. I only want to recalibrate the speedometer so that its correct and so that my odometer doesn't rack up the miles. What's the cheapest way to go about this? I've read a little and found that hptuners can do the job but I'm not familiar with how to operate it, nor have I found what and where to buy it. I also found www.pcmforless.com that can flash the pcm for $150.00. What are my options and where can I find them?

Find a used Hypertech programmer in eBay or CL. You can use that to recal for the 3.42s.
