lol, well your doing pretty good then. do you log backpressure? if you do you can do MAP/EMAP for the Y axis on the fuel table for a much better model of the engine VE. they are expensive to buy but you can get away with using a long piece of tubing and attach the sensor at the end of it. This will give you a solid value to use for turbo sizing and you will then be able to tell when adding boost is no longer effective.
Nice to have even if you dont use it in the fuel equation..
another great one is monitoring the CLT pressure, you can use any passage in the block that will accept a pressure sensor. Just log the pressure and view after the run or setup a diagnostic light to come on when the pressure rise or delta value is high, this will let you know that a gasket is failing or a head is lifting BEFORE you lose the engine.
