Hi all, I have a 1989 GTA 5.7. I have an altered one that I think is programed wrong and dont know what to look for. Im just wanting to find a stock prom. I belive it is a AUJM prom. Can anyone help? Or guide me, I was thinking about maybe aftermarket? Im kinda new at these older computers.

 

I saw this on E-bay today. AUJM prom 8-4-08 20:26 CDT

Item number: 150279251890
For sale is a TPI Hypertech Performance Chip is working condition. I bought it to put in my project rig, but I stuck with the stock chip instead. I was going to build a hotter engine, but stayed with the stock engine. It is not a radical chip, but changes the timing curve and injection pulse times. I'll include a stock chip also in working order. Please email with any questions.
