The important part in tuning is making sure 100% load is actually 100%. After that it's all down hill because the PCM calculates everything correctly for you.
See, that is what I asked you earlier! Is the pressure ratio directly equivialent to engine load? 
I started doing the scaling based on max pressure ratio but I think it won't be that simple when I think that the volumetric efficiency is definitely not linear with rpm or with boost. The factory load values are very non linear with regard to fuel and spark which corroborates this assumption. Oh well, it'll be in the ball park.
***Edit***
After some searching it appears the lightning boosts at up to 8psi stock, about 1.54 pressure ratio. That would make sense to use load values slightly higher.
