I have 3" dp's and I dont seem to hit 10psi until 4.5-5k. No boost controler. No boost leaks either. I do not however have the stock boost jets installed, just straight 6mm hose. I didnt know about the stock boost jets until I changed all the lines. Do you think this direct source of boost to the waste gates is causing this exagerated time to build max boost?
