TPIS system tuning
Recently dropped 383 engine in 1991 base corvette. Complete TPIS intake and headers installed. Can't get engine to run properly. Within 1 degree of timing either the engine will not idle or will not run smoothly after 4500 rpm.
TPIS has been no help. Two GM mechanics have looked at the car. Replaced distributor assembly - no change. The car is at a shop in Wilmington, DE. At the point of deciding whether to trash all of the TPIS intake components and install FAST EFI. Of course installing FAST EFI will require us to basically rewire the whole car to analog and install analog dash.
Need any input regarding tuning TPIS systems. HELP PLEASE!!
