Ran it on the dyno today. About 32psi, very conservative AFR and timing. Not too bad, but I was expecting a bit more. When I get a chance, I'll clean up AFR and throw some more timing at it.

What details do you want? Basically, I am using a JDM MAP sensor and GM AIT sensor to measure air flow instead of the stock MAF. My ROM is patched to do all the calculations and to disable any CEL associated with removing the MAF sensor. The only physical modifications required to do this is to wire the GM AIT sensor into the ECU in place of the stock sensor signal lead. Then use a 1kOhm resistor in place of the baro sensor. Finally, swap in a JDM MAP sensor. I'm trying to get someone to look at my ROM and see about porting the patch over to other ROM ID's.

Tell me about it. 2.3l AND the full stage 3 head, boost plummets quick. I really wish I could have gotten the red instead, but I received the green 1 week before they announced the red was available.

Tuning is done via the stock fuel map and a MAP to MAF VE table that allows me to make the load curve look however I want it to, which is why I can push 30+ psi and still keep load under 300.

Good stuff. I've been waiting to see how things would turn out.
So do you think you will try and get a Red, or larger turbo? Or are you happy with the powerband as-is?
