Dealer thinks its a Intake issue and Stillen says its a vacuum leak or defective EGR. When I hammer on her from first to second she hesitates as though my foot is off the gas, then catches up and goes. Anyone else run into this issue? Tired of the damn check engine light turning on and the run around from the dealer. Should i take her to get tuned? Any help would be greatly appreciated!

I'm having the exact same issues after getting my Stillen CAI installed this weekend. How did you fix it or does anyone have any suggestions? The car sits at 1K RPM, hammering off the line in first; very slow off the line and the car hesitates for a moment before kicking in, and Service Engine Soon light is constantly on.

I checked all the pipes and tightened all the clamps. My engine also has a fast ticking sound coming from the engine. I don't remember it sounding like that when I first bought it last month. It is still under warranty and I highly doubt within a few weeks that it would be spark plugs. It definitely seems like the Stillen is at fault. I'm debating taking it off bc my car is definitely slower >3K RPMs.

Your car will hesitate if you have a check engine light on. Clean your MAFs carefully and see if it helps. DO NOT TOUCH THE ENDS OF THE SENSORS! The ticking was probably there already but more noticeable since the engine is sitting at a higher RPM. Its pretty normal for our cars. There are probably hundreds of people on this forum with the Stillens sincce it has been proven time and time again to make the most power with no issues. Its something that can be resolved with keeping the intakes. You just need to pinpoint what it is.
