Mikey, we will probably have you tune my wife's '08 WRX, on the initial tune, we had problems getting it to hold boost. We weren't asking for a lot, 16 PSI, but we never hit it and what we did get would bleed off to 7-8 by redline. EBCS was mentioned as a solution, as was adjusting the wastegate. Adjusting would be considerably cheaper, so the question is, is the EBC necessary? If so, I would like your recommendation on which one to get.
