We're not hiding just locked away in our cells working madly on various projects. (More pizza, donuts and Coke Cola would help 
)
Our current engineering workload is quite high given the number of engineers we have and the amount of R&D work occurring in parallel. The actively worked on projects include EVO UTEC software, Gameboy, Tuner sensors, STi UTEC, plus a number of "other" projects.

My only concern using the factory solenoid is that it's limited to 23psi. Thats plenty for now, but I plan on upgrading to a BR 580 in the future so I am trying to plan ahead for that.

Actually its not limited per-se.. with the ABC you can adjust the bleed rate so that your minimum is a certain point, and your max is higher.. in closed loop control you can tweak it, especially with an aftermarket turbo to much higher, since it also a factor of the wastegate spring pressure too..

We are here lurking and working hard at this and other projects.
Jermaine has even taken to mildly modifying the EVO UTEC software code that contains the fuel map needed to allow the UTEC to function with the new software.
The code and fuel map are getting VERY close. We have a customer’s evo that should be on the dyno the end of this week for some tuning. Jermaine and I want to tune this car with the new software.
As crazy as things are around the shop, you guys are always welcome to call when you need help. We'll get to posts here a little more in the future, but it is encouraging to see how well you've carried on without our direct intervention.

I've never had the chance to look at the evo utec, and wasn't aware there were real differences, what else don't they have in common?

There are a few differences, there's a new firmware due to be released for the EVO Utec that will have the injector scalling, etc..
The Tuner setup adds a column to the standard UTEC data-1 log (and shift-data-1) for AFR.. AFR logging using the EVO's narrowband O2 sensor isn't very accurate at all (its actually not very accurate on the WRX/STI either) but I suppose they determined for one reason or another not to include a O2 voltage or Lambda for the narrowband since it just gets "Superceded" by the Tuner's output when its detected.
In other words, with the TXS Tuner and UTEC, the logs will have accurate wideband AFR in the data-1 logs..

I see........ the old wrx utec didn't have injector scaling either. I guess to be really accurate you really need a scan tool so you can read your actual fuel trims and then zero your map to that, however the injector scaling is really the next best thing.
As for the tuner, I just was confused thinking that when you added it to the evo utec it didn't bring up the afr column.
thanks for the info.
One more, at what throttle position can you start your map with the evo utec, the old wrx, and the new sti models both differ, just wondering????
