Hey guys, I'm the owner of the car. Thanks for the comments. 
To answer how much this cost, lets just put it this way, it wasn't cheap.
There were a lot of setbacks and things I had to do in the background...
I have to bring it back to tune for 91 oct. So I don't have numbers yet.
The car was tuned at UMS Tuning in Mesa, Az. Yes, this was on q16 gas.

thanks for posting up antonio, take some vids!
actually (2) 40R twinscrolls will be in your driveway 
. start making harassing phone calls lol
it was tuned on Q16 race gas at UMS -- they are an excellent shop in Mesa, AZ and their dynapack is well known and consistent. Modified Magazine uses their shop as the benchmark for their annual tuner shootout. more info on them here: http://www.full-race.com/tuner-shootout-09/
if you are asking if its possible to make 600ft lb at 3500-4000rpm, no this is not possible... its still a 2.4L 4 cyl engine. The only way to make more torque faster is to use a larger displacement engine, and/or a smaller turbo at higher boost which would fall off much more in the high rpms and not make as much HP... this is about the burliest evo powerband ive ever seen - or perhaps i misunderstood your question?
yes the 2.4L engine is high displacement and has an aggressive rod length: stroke length ratio which means the pistons accelerate VERY fast and this will definitely will cause the torque to drop off. As far as the turbo, you could run it as a singlescroll to stop the torque dropping, but then you would lose the huge torque ramp up in the lower rpm - and thats where you spend 99% of the driving, so it would be a bad tradeoff

39psi on Q16 race gas, he will do a pumpgas tune shortly
i think youre miissing the point -- it has an earlier boost threshold, makes more power and has a correspondingly larger powerband with much more area under the curve. FWIW its not that big of a turbo... a 40R is only 63.5mm inducer/88mm exducer. For comparison sake a 37R is 66.7mm inducer/84.7mm exducer
difficult to believe? what is so difficult to believe about two totally different turbo systems with totally different mass flow rates / pressure ratios having different results? ill have tony at UMS post a boost log when the car is back for the pumpgas tune...
