It's still creeping in the upper RPMs. We didn't hit the 25 psi until right at 7500. I was joking about the lag also. It spools much faster than I would have thought. At peak HP I am not sure what boost we were actually at. We had the base timing set at about 0.5 degrees. So we were running around 13 to 18 degrees of actual timing depending on the RPM. The stock timing map trails off in the very top RPMs where we hit max boost. It also starts off low, so we didn't have any problems in the mid-range. We just had to be most careful in the 6000-7000 range where it wants to run the most timing. The creep made tuning a little bit of a pain, hopefully that can be fixed. Should get more interesting once he gets his sheetmetal intake and EPROM ECU, then the power should keep climbing some and we should be able to modify the timing tables in the ECU to what we want.
