thanks guys, i just had the same problem and just figured it out. i replaced the stock line too. and i was at 12 psi. only problem was that i got the boost gauge after i ported the stock o2 housing. i just maybe figured that it was cause i was at 6000 feet, but i felt a loss in power after i did the work. you guys saved my life, i was so confused!
