I've drove two different VP trucks with the Quads. Worst fueling curve I've ever felt and more than inadequate. One of the guys sold his drag comp to get the adrenaline and has hated that decision from day one. He was amazed how much better it ran with his Jammer 5's and HX40 with just a Smarty than it did with the Quad. To each their own, I know if you have good luck out of it, you'll probably like it, and keep using it. I'm not lucky enough to win any kind of lottery, let alone the Quad lottery of whether you get a decent box the first time. My advice, which isn't worth much, is to stick with what you feel best with. If I were you, I'd use the Smarty and either the drag comp or the TST PM3 or Competition version. Just my $.02.
