| It allows the turbo's to maintain boost during shifting as the wastegates/recircs are generally not opened like a standard (foot off the gas) shift, plus there is less air resistance in the intake due to open TB's. As far as cost effective... Not that I have found (yet). Closest I could conjure when I looked was an MSD DIS-4 and rewiring for a waste spark ignition.
