1) Would you be able to email me a couple of pictures with some dimensions of your plenum written on.

I will then run a series of CFD tests with the throttle plate at different angles and publish the results on PF.
2) You could send me your inlet and TB and I will conduct a series of tests on a flow bench with the throttle plate at different angles and again publish the results on PF.
I will be fair and impartial and will publish all results regardless of the out come.
if your point is valid about the throttle body (which scientifically it is) then could the problem not be resolved by rotating the TB 180* so at part throttle, the air is directed down into the plenum rather than into the number 4 cylinder?
