Kenne Bell Boost-A-Pump?! Is this the best idea? Anyone with f/i running this?! I'm told once I get past the 450 RWHP or so I have to use this or upgrade to GT500 Pumps or better... Does anyone have this Boost-a-pump system?! Whats the general feelings about it? It seems cool and, theoretically if it works correctly it's an awesome product!? ?
