I found another fix for my surging problem. My car would pull then it felt like the car quit boosting and surgred in power. I replaced the "Boost Valve" in between the waste gate and the turbo and it helped allot. I had allot of oil blowing into the intake system and probibly pluged the valve.
I got bored last night and built an intake for it. INSTANTLY faster and no surging. I guess the filter was dirty or just flat out not good enough for the turbo's needs. NIGHT AND DAY difference.
I read that adding a intake will up the boost and cause the computer to get pissed and shut you down... It doesn't appear to be doing this in my case. I am assuming its because I am in 5000ft alt. so i am guessing i am not seeing the same boost you guys are at sea level.
