This came about from the thread about Brian's wastegate location Here is the last post:
why do you think it would run lean on #1 if the wastegate is on the #1 runner?
With the wastegate open you are going to have a LOT less restriction on the #1 runner compared to the other cylinders. You will have an open valve that is venting the exhaust gas straight out and not through the turbo. The exhaust has less retriction so more air flows out and allows more air in (valve overlap, although it is smaller in turbo'd cars). More air in means it runs leaner.
#1 and #2 tend to run lean anyways, it would make more sense to put it on the #4 runner if you are going to put it on the exhaust manifold.
