Black STI, thanks for all the suggestions. Matt at DSG tuned the car and I'm extremely happy with how it runs, this was just something to contemplate as for some reason, around 8psi, 3rd gear, v7 JDM STi 6-speed, the wastegate is starting to open. Now that I switched from interrupt to using both ports on the wastegate, it isn't opening so early. I let off the go pedal around 12ish psi anyways, but I'm at school near Buffalo, NY, quite the drive from home.
Since I have it doing what I want now anyways, I'll look into it closer and discuss it with Matt after I graduate in December. I'm probably moving away from EWG VF39 to EWG 20G/Green or IWG 20G/Green, not terribly sure yet.
