Evo IX stock turbo, approaching the limit

Evo IX stock turbo, approaching the limit
Well, I took my car up toe Knoxville TN to get some dyno pulls for submitting my NASA TTS car classification info. After the first round of mods, my car was Mellon tuned, made 335/300 and drove great. On the second round of mods, I did the tune (road) and the Virtual Dyno graph showed me 377/361:
I was curious to see what an actual dyno had to say, and here is what it made 379/380:
The boost/AFR plot shows me the stock tubo is also just about out of lung:
That is some pretty heavy boost taper. But for a stock motor/cams/turbo IX it makes pretty good power. And I have run this tune all year through multiple HPDE's without a hitch.
The power mods:
3" full exhaust with RTP and SS MAP O2 Housing
3" ETS Intercooler and LICP
Hallman MBC
Ported OEM Ex Manifold
RC750 Injectors w/ Walbro 255
ETS Intake and Cone Filter

Depending on how much weight I get out of the car, tire size and other factors I will be limited to something in the 380-400 awhp range for NASA TTS. But I do want to get a better power delivery and extend that torque curve.

You need better boost control for sure! That boost taper is terriable. Its not that you "need more power". Its the fact that you can gain power from 6500rpm and up making the car pull harder and longer. PERFECT for RR and AC! Plus its a cheap mod. Its a no brainer.
