Default Which Ems if money were not an issue?

Ok I currently have an 04 WRX wagon. I have a borla hush cat back, and I'm waiting on Cobb to send me Down and up pipe. (Down pipe is back ordered) When I install the Down/up pipe I'd like to install an EMS. Right now I'm looking for an STi donor wreck to do a full swap. (if anyone can help me find one I'd appreciate it) initially I'll be swapping everything, but the engine. Which will go to the machinist for head work and boring and sleeving. This is all down the road, but I figure I might as well invest in a really good Ems now. So my question is two part. One I've been looking at the UTEC, AEM and Element systems, are there any others I should consider. And two, Which should I get and more importantly WHY?

The mechanic that I'll be doing all this with has a lot of experience with the AEM, but I notice that it doesn't seem to be too popular with the Subaru crowd. I normally don't care to much about going against the grain, but in this case having a large community of users to share experiences with could be a real plus. The UTEC seems to be the most popular, but that may have a lot to do with the fact that it's also the cheapest of the three. I'm not worried about the price, only about getting the best product with the best support.

Autronic, Motec, GEMS if money isn't an issue, but what do you need the ECU to do? AEM isn't as popular because of the products that TurboXS, ECUtek, Cobb, Vishnu, and others sell. They are pruven, and everyone (99%) of the reputable tuners use them and know how to tune them well, and have a wide variety of maps for different setups. That is the big thing is access to a variety of maps. Everyone has a little different setup, and every car is different. Some need an ECU to do certain things besides the norm, IE scale big injectors, water injection control on a spare solenoid, or run modifications or bolt ons that the normal ECU, or a flash cant handle. So some go the stand alone route, to have flexibility over every aspect of tuning the engine.
Do your homework, decide what you want out of the ECU, and go to a tuner you trust, and look at the different tunes that they have done in the past. Don't put what everyone on this board says about one tuner or another against the shop you are going to pick. Go there and check them out first, have them show you the faciltiy, meet the person doing the tuning, and discuss what your goals are. The main goal of any good tuner should be good power gains with a safe tune.

Sorry a little OT, but that is why everyone here isn't using AEM, Greddy or whatever. Not saying that those are bad ECU's, but accessibility and map diversity, and how you are applying that tune. Because of that UTEC, ECUtek, and COBB work for about 95% of the users out there.

If money weren't an issue I would be looking for the best tuner in the country and use what ever engine management he felt was best. So in my case I'd probably end up with an Accell DFI.

Also a question many people neglect to ask is if it is OBDII compatible. Hydra, AEM, MoTeC, and Accel will make your car a race car if you line in a state where you need OBDII to pass emissions.

What do you guys think about the Hydra EMS? Can I get that ECU and run the same map and stock 06 STi then after I get some parts I will go to a tuner.
