The Vac Lines were the same EXCEPT for the EVAP Sol on the Left bank.. I cut out the PRVR Stuff and left the EGR intact..
It's strange that the Idle setting has you disconnect the TPS Switch.. but it is a way different ECU..
I'd look at using the O2 Sensor Voltage to adjust Air Flow by way of the Idle Stop Screws for the T-Bodies.. that is the way I set my Idle Air Balance on the 3 NA's I have..
