Looking for a stock prom
I am trying to determine what the PO did to the tuning on my car (fan controls, etc). I have a scanner, but they dont tell you everything. I am looking to see if anyone has a stock 88 or 89 5.7 TPI AT chip lying around that I can get cheap (will send it back if you want when I am done if you want). 89 would be prefered if I can keep it.
Thanx in advance.

88 and 89 proms are quite different. 89 has vats and different warm up program as they did not have cold start injector. You need an 88 prom.

My car does have VATS. If I use the 89 Prom I can get rid of the Cold start Injector.
