my cousin has a auto 93 z 28, slp used to make a chip for them. He wants a chip and I said that one of the guys on the board could probably do it for him, but I wasn't sure if they could do it with their software cause 93 is a 4th gen (a odd ball year)

 

You can burn the chips like the pre-93 fbodys. Its just that the .bin file that you are uploading to the Memcal will be different. You will need to get TunerCat to be able to edit the parameters in the bin file. The definition files for 93's and pre-93's fbodys are different.
