The cold start is still a little rough, but after it warms it idles and runs great. I'll take it back in couple weeks for more tuning and a pull at 1 bar. If my tuner can't get the cold start to work better, I'll probably put an air control valve on it.

Craig, I hope you're wrong

If boost to hp is a linear relationship (I have no idea if that assumption is correct) and zero boost is 200hp (another guess), then 1 bar would be a little over 500rwhp.

The lambda pretty flat at .8 from 4000-7000, but it's a little rich from 2800 -4000 with a lean spot around 2200. Still more tuning to do, but we figured it was safe to put some miles on it at the lower boost.
