At about 70kph(43mph) in 4th gear while cruzin' I notice some hesitation. If I accelerate past 70 it disappears. Its almost like a stutter being caused by a lack of fuel or something. I have an AEM CAI, FC TB, JG Header, Stage 3 cams, AEM Cam Gears, & Wires. Any one have the same problems or any thoughts.
