Remember that boost is a measure of resistance in the inlet tract. So with his larger cam, the engine is allowed to flow more air and less resistance, hence the drop in boost.
Going from the stock 190/191 cam to the 205/212 gives 15* more duration on the intake side. lift has gone from ~.450" to .547 also.

On Page 2 of the Radix Truck Instructions it clearly states: "Drive belt is a Gates #K061120", which of course translates into 112".
So yes, it would appear that you've installed your first wrong part. Is that kind of like your first ding?
