Ok today I installed a #11 plate/elbow as per Pier's instructions every thing went well but I doesn't seem to run much different than the plate I took out (truck ran well from what I can tell, I use to drive a 6. 2) I'm not sure if the plate I took out was stock although all the nuts and bolts seemed to be original paint. Minimal if no smoke so I adjusted the star wheel 3 times, 3 clicks ea toward the engine, and no change. AFC and #11 back in the same place as what was there. The plate I took out had numbers on it (24287), any ideas if this is stock?. Here are profiles off both plates. The gov lever comes in on the #11 about halve way up the first slope. Boost max's out at about 32 and ET +1050 pre. Any Ideas? Thanks.
