i had this exact same intake before and switched to the simota intake because the check engine light came on and my friend said the engine light is a misfiring code. The only time i felt a problem was on the cold start every morning, the car would vibrate a lot. Is this the what you are referring to as the surge? I love the sound of AFE so much better than the simota
