Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially and if everything is stock, then the most likely suspect would be an air issue through the ram-air system. These are vacuum-operated system and/or ECU-controlled tunnel butterfly valves that allow/block air entry depending on the throttle opening and RPM.Please post back results / observations of the above once checked.
