1989 gta prom
Hey GTA Source page, I am a new member and I have a 1989 GTA that is basically a track days car but it is street legal. However now that I live in TN it is no longer street legal because it will not pass emissions.

Which leads me to my request, I am needing a PROM for my 89 5.0TPI 5 Speed GTA. My company moves me around and over the last couple moves my PROM is MIA!! Does any one have one for sale?

I hear the 89 is a one year only because of the VATS and the elimination of the cold start injector from previous years.

Please e-mail me a or reply to this post.

Do you need the Calpack or just the PROM file?

I need the EPROM. The GM part number is 16133630 which is for my car because of Fed. emissions. I found an NOS 16133632 which is for a 89 5.0 TPI 5 Speed with California Emissions but I do not want to use that for my GTA.

I either want a good used 16133630 EPROM or NOS EPROM. Race Krafters in PA programmed the EPROM I am currently running and it might pass emissions with that EPROM.

Does anyone out there have the ability to program an EPROM to match the 16133630 Federal Emissions EPROM?
