Are you running it with the new intercooler system as well? Did you do anything extra from what comes in the base kit?
That kit is calling my name. I'm wondering if it will get me better mileage?? $3000 seems a bit steep but if it does what it says it could be worth it...

Here's a quick video I took when I was still running the 35" MTR's , I'll have to try it again with the 37's.
I haven't seen a tub-mounted rack before...who makes it?
