So, I've come to the recent realization that my HX35 isn't really cutting it in the airflow department, so I'm considering upgrading to a slightly larger turbo. I've got two options, both of which have similar prices to me right now; a genuine HX40 with a 16cm housing, and an ATT. Either way, they'll be run with WMI, 3" intake plenum, and more than likely an intercooler. Not really looking for high boost numbers, but I'm trying to keep it in the 15-20 psi range. Any thoughts/opinions on either of these setups are appreciated since I'm trying to figure out the most efficient option for my truck.
