As the title says I was on my way home today and during acceleration my boost gauge goes up to 10ish psi and flutters and normally it goes around 15psi, so i can tell a difference. I havent had a chance to look at things closer yet just wondering if you guys had any ideas. I can notice it doesnt accelerate as hard and I cant really hear a leak but havent had a good chance to hear it either. Its an 07 s60r auto. I run it stock just with the air intake filter cover off but havent had this problem before.
