different TPI setup from 85'-88' to 89'-92'
What is the difference between the TPI set-up from 85'-88' to 89'-92'? I was at a swap meet and didn't know the difference.One other thing, my MAP sensor in mounted on my plenum,right rear side, I haven't seen other 91' 5.7L camaros like it

85-88 TPI's have a cold start injector on the drivers side runner, the 89-92 TPI's dont... Also, the 85-89's are Mass Air Flow, the 90-up are Speed Density and have a MAP sensor. Hope this is helpful...
