sst pcm chip

Hey guys, I have a pcm chip and Im trying to figure out what it is. Its a sst, and it says custom efi tuning by alvin anderson chips@pcmforless.com I got the chip as a package deal so I really dont know much about it. Thanks for any input

Is there any other numbers maybe a date or something? If so you may be able to contact alvin at pcmforless and he might have some type of record of it. Other wise I wouldn't just throw it in the ecm,that is considering it is a 93 chip car! One more thing you should create a sig so everyone with ideas knows your upgrades,year,make,etc...
