nice. but i have a few questions:
1. is stg1 like stock where the boost solenoid needs to see boost? (or did bypassing them like you did remedy that)
2. where does the line with the check valve go to the turbo? and which way does that particular check valve go? (obviously the brake booster needs the vacuum so it is self explanitory)
3. are you noticing timing being pulled?
4. do you need a guinnea pig for your piggyback in california?
