Good stuff. I'm loving seeing these informative posts around here.

I do really like your "step by step" breakdown of tuning boost. I'll note a couple things:

1) This breakdown is really geared to 16bit ECU's, the 32bit ECU's have additional tables which make tuning boost quite a bit easier.

2) When tuning both types of ECU's (and really any turbo), I would highly recommend that everyone keep the "boost target" values within range of what the turbo can hit at that RPM. I often see guys who get lazy and place very high boost targets in the low RPM cells. This leads to integral windup and hampers the ECU's ability to control boost.
