Projection

     I wouldn't do this at all. From what I recall, the EGR feed is through 
     the center two exhaust ports in the head. So, assuming the intake 
     manifold is properly restricted to bias the flow through the intake in 
     one direction...you will only be reading the O2 output from two 
     cylinders. If you stick an injector in one of these cylinders and get 
     a rich reading at the O2 sensor, and the ECM leans out ALL the 
     injectors...you will be running very lean...which is not a good thing.
     
     TTYL!

Not a bad idea, can anyone verify if this is feasible with the Chev TPI as well.
