I went into this build hoping for 400's. 5 minutes with Brad at Engine Logics told me that was not going to happen with this turbo. The first run was done at wastegate spring pressure and a minimal tune to make the car safe to drive to Engine Logics. I am happy where it is for now, but will probably be looking for more soon. The power level feels about where it was on my first build of the Legacy (before I took it back to stock to sell.) After getting lowball offers, I decided not to sell and make the car what I wanted it to be. That is where we are now.

I also started with a transmission issue, that is NOW SOLVED. Brad said he had experienced the same issue on 350Z and G35's. It turns out that the load scaling being modified from stock throws off the TCU and causes shifting issues. Back to business. There were no real issues aside from one small vacuum line coming off of the evap system.
