Ideally you want to work with the MAF sensor voltage with a little
headroom!!! (same with injectors).  If you have an 850 kg/hr meter
(regardless of size) and are making 300 hp and you are getting almost 5 peak
volt on the MAF (this is what the EEC is seeing) you need a different curve.
You'd need to jump up to an 1100 kg/hr curve/MAF, and try to limit your peak
voltage to maybe 4.2-4.5.  You can tune better (and the EEC can trim fuel
better) when you are working on the lower end of the curve.
