Hydra all the way with something that big. Sure, there are high HP cars out there using the UTEC, but they are all using larger MAF tubes, and all of them have the associated "issues" that go along with the larger MAF tube. Those issues being, drivability that isn't near as good in a lot of ways.

You can't control throttle pump with the UTEC. Every time you tip in to the throttle, you run lean for a split second, then it catches up. Because, with the larger MAF housing, you're fooling the car.

You have to deal with the "crossover point" with the UTEC. Closed loop to open loop. That doesn't exist with the hydra.

My car, I don't even have a maf tube. Filter is clamped right on to the intake tube, and my V8 intake manifold has a temp sensor I'm using (instead of the one on the MAF). I end up with much more accurate intake temps that way as well, as the temps are post turbo (and intercooler for that matter).

My car is more drivable now than it ever was, except maybe the day I drove it off the lot

The only reason I can see not getting a hydra is if you aren't willing to put in the time to learn it, or don't have somebody in your area that can tune it for you. The engine management is only as good as the tuner obviously
