Reason I was leaning to Nizpro was, heard they have less drone, but stil make big power with the 4inch setup, this is a workute, have been known to go too far with cars in the past and want to keep this rig nice and quick but not uncomfortable to do the work duties.. Looking to also fit the process west stage 2, race intake, fuel system to match and leave it at that, from what ive been reading I should expect 360rwkw to 400rwkw pending boost.
