I got 13rwhp with Invidia CBE on a DynoDynamics dyno.
Anyways, i had Stillen S/C on my old 350z, and i didn't like their crappy RC 7th injector and their control box that required some wires to be cut and solderned to the ECU harness, what i really like about GTM kit is that they made it the way people like it, and you get your own ECU reflashed and tuned for it, which is much better than having a piggyback unit.
The price so far is not that much between the 2 kits, but i heared that Stillen price is for pre-orders only, after release the price well be around $6700, that's what i've been reading on the other thread.
But anyways, in a matter of few months we'll see both kits on the same car on the same dyno for comparsion, it's too early to say this better than that, so far all we know now is the price.
