CHUK, Have you installed the big dog intakes yet? it sure would seem the ported "Y" and increased intake flow should some decent power. Did you do the "Y" with a dremmel type tool or do you have access to a machine shop? The tweaked intakes seem like they should also add some power but it seems not that many of the guys here have that mod. Even a drop in psi should happen with the better flow and if that is the case I would think the additional flow again should net more power than I have seen. So if the big intakes are not installed are you getting them on soon? Dyno results would be interesting as you would be meticulous about getting the best from these post SC mods, look forward to what you are able to extract! Sweet
