But yes, you're right, it would ultimately depend on what I want more, more peak power or more power everywhere else. I haven't made that decision yet and I think comparing two dynos would be the best way to make that choice. If I'm only losing a little bit of power down low but making a decent amount more at the top end, then yeah that would probably be what I'd go with.

I'm interested in your supporting mods, too. Curious about the reason of lowering boost. I've been running 13psi on stock block of filter on and pump 93 gas for up to 6500 miles with no issues. What fuel are you using? What exhaust system (cat/catless/header/test pipes/cbe/pipe diameters) are you using? What fuel system are you using? What ignition timing is with your car? Increasing volumetric efficiency by means of better intake and exhaust can benefit power without the need of too much boost and is always good to do so, but it's better to let us know your mods first so that one could comprehend the reason. Lowering boost can be achieved by either a larger jackshaft pulley (serpentine side) or a larger supercharger pulley (supercharger side).
