Both can be purchased from http://www.deatschwerks.com (or some local vendors on here). Both are direct drop in. You will need to scale the injectors, but your tuner SHOULD know how to do that
Not enough fuel and you ain't going to make power, simple.
What does the butt dyno say anyway ?
Personally, and only because I've been doing this a while, I would ditch the Ecutek and get someone like Matt (aka Kido) or Eric Mineheart (Torqued Performance) to do the tunes. They get you to take logs and will send you an updated ROM which you then flash yourself via a Tactrix (https://www.tactrix.com/) cable/openport device. Ideally an external wideband AFR sensor as well (I have a zetroninx zt-2 (http://www.zeitronix.com/) which can be read by Romraider (for logging) and hasn't failed me in 3 years !!).
You just need to be prepared to go for the drives and take the logs. No biggie. I personally use Eric as he responds with the new tunes same or next day. Knows his stuff really well. Matt is good if you want to go outside the box and use a custom ROM e.g launch control. Can be hard to get hold of sometimes and non-responsive (personal opinion).
So true ^
If that’s the stock pump etc it’s over 10 years old... Do the in-tank bucket filter at the same time...
Also take a look at similar member profiles/mod lists on this forum, as there’s plenty of proven formulas for getting to a safe 180-200atw.
Another essential aspect of safe tuning is road tuning. That’s generally how Matt tunes, and how you will tune if you use Eric. I outlined the process in this post... viewtopic.php?f=56&t=20196&start=0
These guys really know Subaru tuning!
And do check if your boost controller is properly hooked up, that turbo should hold 18psi to redline no problem assuming no leaks and proper setup & tuning.
