would it be worth it to upgrade to the new Quad X2 race? I need to send my regular Quad race box in to get the pressure only tune anyways. Is the boost fooler any different and does it spool the turbo any faster. I love the way my truck runs right now except that I am not getting as much boost as I think I should (40-42) and the turbo spools a little slow. If I feather the pedal it spools fine but if I get aggressive with it I will lose power and just belch black smoke until the turbo catches up and then it will clear up and go. It seems that I am getting too much fuel at first and then it seem like I am not getting all I should on the top end. My rail pressure shows 22,000-24,500 psi at WOT so I am not draining the rail, but it seems like the turbo needs more drive pressure at WOT like the engine isn't getting all the fuel it can use. I am leaning towards different injectors but can't afford them. I can afford an upgrade to an X2 though. So I guess I am asking if the new product will help or just be the same. Thanks, Tom J.

I am stacked with the newest downloadable software on the Smarty(Dec 13). I think it is the 4.11 aftermarket injectors and turbo with wild TQ management. I run it on level 8 until I can get a pressure only tune on the Quad race and can run level 9. Where's that 230hp tune? I can hardly wait.........

I think it's worth it. For me, the USB download capabilities for future updates is worth alot.
