There is still some power to be had there. Also, triple check all the vacuum lines, you will be surprised with what you find.
Mine idled between 14-15 with a little crack in the line that runs from the elbow to ICV, and thats with the 100lb tune and zero adjustments to the base map.

If you lean it out up top where it dips to the low 11's you'll make more power. You can safely run 12:2 to 12:6 on your engine.

much easier said than done, unfortunately.

Austin, from Kansas had his turbo s50 remote tuned on Friday. At 15 PSI on a conservative tune (per his request) he put down 430 HP and 400 ft/lbs on a Dyno Dynamics!

The original B34 that was in the car (which is for sale!) put out a respectable 173 rwhp and 188 rwtq. Un-tuned, with a stock 179 ECU and AFM, the B35 put out 196 rwhp/216 rwtq.
I'm quite happy with these numbers and even happier with the way the car is running.
The Miller WAR software is pretty dated and makes me jones for a Megasquirt now that I actually know what I'm doing. The idea that you can tune in real-time is pretty appealing. Maybe that will be a future project.
