I have just installed the s4 cams in my car, I have put about 80 miles on the car driving like a granny due to break in period. The idle is realy bad, I know that i have to get the ecu to correct this problem,but not only is the idle bad but the car basicly runs like ****, the car hesitates around 3500 to 4500 rpm. Anybody have similar experiences with the s4's? The car seems alot slower too me , maybe the timing is fuked up. Need info from those who have the s4's
