So on my 2010 MR I have an AEM Intake and Invidia N1 exhaust. When I go above roughly 60% throttle I am getting a violent rocking from front to rear. I'm thinking the car is leaning out on fuel since under 60% throttle it has no issues. So if this is the case should I get larger injectors since I'm still running stock injectors to resolve this or should I just get a tune?

 

You have any way to show us a log? I highly doubt an intake and cbe is going to cause this, there is definitely an underlying issue. Did you double check all vacuum lines are connected??

 

AEM intake will lean the car out without a proper tune. Also make sure to check the fuel relay and make sure the FPR hose on the intake manifold didn't pop off.

 

are you using a boost controller ? are you using blow-off valve?
