What excites me most about the X-47 is how the power is described as being able to build until 7500 rpms. Currently and on my x-37, the power increase once past 5k rpms is definitely noticeable above the stock turbo, but to me it is only good to about 6700 rpms and before you might as well upshift.
If the X-47 can truly hit boost and build/hold power from 2200 rpms up until 7500 rpms, then wow.....
Some guy on the internet asked why not just pony up the few extra grand for DHM, and although I firmly believe that DHM is the current top dog Fiesta ST turbo system manufacturer, I went with the X-37 for simplicity, cost, reputation of Pumaspeed, and not personally requiring or wanting what a more advanced system would provide with wheel power.
All in all and what my ultimate goal for my car is, is to achieve a true 300/300 at the wheel without meth or aux fueling. I don't mind having to blend for E30 since my FiST isn't a DD, but it sure would be nice to be able to make 300/300 on 93 octane alone.
