Prior to rebuild my compression was around 160 all cylinders and turbos in good shape. I have dynos of my stage 5 doing 365 rwhp and following your "stage 5 average" perfectly, however personally I dont think they are accurate. Plus all my dynos are at sea level which I think as discussed a few times here makes a fair difference to results. If I went back to the same dyno and redyno'd then it would follow your stage 5 curve exactly. The point though is on the same dyno it follows the curve of the stock turbos exactly, hence my claim it spools as well as stock.
