A nissan tuner in Florida built a response tuned car. Made 370 rwhp at 13 psi and full boost at 3900 rpm. (just so you guys know...Im running 12 psi on the stock turbo. I make ~250 whp and not much sooner) But he's keeping the exact parts selection a secret for now. Some astonishing accomplishments are being made. Im just letting others pave the way.
Another guy who is building a drag car hit 370 at 12 psi..but full boost at 5500 rpm. Here the dyno vid. (kinda long...just FF to the middle) Cant wait to see what it does on 30 pounds.
Oh, and Eric...all that reverse engineering that hackers do to ecu's has been done. We have fully programmable factory ecu's now. Remember that Biki-Rom guy? He used to make ROM programmable ecu's. Now people can plug the ecu in directly to a laptop and tune away. But I have my Power FC already which will do the job just fine.
