It all depends on how crazy you want to go. For stock turbo bolt-on types, I'm leaning more towards the vf34 sti turbo that's capable of 350 crank hp and still lets me use all of my aftermarket up-pipe/down-pipe stuff and my fmic piping. I've honestly never seen too many ej20's being taken over that power level anyway (most of the big power setups use the sti ej25's) and I want to keep it as much of a daily driver as possible. There's even a few companies that make tdo5h/big 16g's that use a special triangle flange housing to bolt to the stock up/dp as well.

find me a vf34

Keep an eye on ebay and NASIOC, usually there's a bunch floating between the two sites.

Nice! Lookin' good so far bro, glad someone's getting some use out of this info on here. I just tried out the RomRaider datalogging program for subaru's, and all I can say is holy ----...I don't know why I even bothered with Logworks2 for my WRX. This program is awesome! It even has plug-ins for Innovate and AEM widebands plus some other ones.

On a side note I just swapped out my old Brian Crower 272's in my Evo for a set of GSC stage 2 cams...what a world of difference! I've got some fine tuning to do, and I really need to find an AWD dyno to see what my final numbers are. Rough guess is an extra 20-25whp over the crower sets at least and one hell of a lumpy idle.

question. do subies blip the injectors at 0% throttle? because i've seen where it says yes, and where it says no. it sounds like a YES, but i dunno.

well, me and sinister downloaded a basemap from openecu's founder, compaired it to my stock map, (it was more of a polished and high/low point smoothed stock fuel/timing, with a little extra boost) copied the fuel/boost/wg/timing maps over, took it for a ripper and it felt stock. turned around, started ripping on it, then the boost started jumping up from .8mpa to right around 1.0mpa. guess it needed some input to relearn some stuff. then we re-read my flashed rom, leaned out the big rich spot in highway range, reflashed it, and i went home. feels much peppier around highway, and i can pull hills at vac or 1-psi vs 4lbs+ (woohoo mpg) vs what it used to be. feels a little faster, but it's MUCH more responsive.

Subie's are a strange breed with it's ecu control. After reflashing there is a 16* timing advance that has to be "relearned" if there is no knock encountered and can take a few days to get up to the full 16*. There is a trick to advance it in less than 10 minutes though...drive the car in 3rd or 4th gear and hold the rpm's steady around 2500-3000 with your foot on the gas and brake at the same time. It loads the engine and allows the full advance within minutes.
As for the injectors being open, it's rpm and load dependent. Under a certain rpm and load the injectors will turn off at 0% throttle, above that certain rpm they will blip on to keep some fuel in there to keep from melting stuff.
You'll notice the more parts you throw on that allow the car to breathe more, the less timing you need to gain power, even if it shows no knock. The past few days I've been working on a map for my WRX that shows no knock with an increase of up to 5* but gains no power and actually loses some in certain spots. I saw the same rich spot you did and I also had to smooth that out, and as long as you have no cat on the car you can lean it out in the cruise AFR range to mid 15's to save some gas.
If you haven't tried it already, give RomRaider a shot for your datalogging, after playing with it and comparing it to LogWorks2 I'd say RomRaider is the much better one for datalogging and gives you the correct airflow numbers instead of LogWorks' faulty numbers and has plug-in's to allow datalogging from LC-1's, LM-1's, Utec, and AEM widebands.

how can i lean it past 14.70? it tells me the value cannot go lower than that

Hit it with a hammer, Jon. That will make everything better.
