So I recently installed a K&N intake and I would drive on the free and downshift and the Rpms would Rev but it seemed like the motor had to catch up to them, I thought that might have been the issue, however today I started feeling a vibration or what felt like slippage when taking off from first gear and sometimes going into second and the Rpms would go a lot higher when I'm accelerating on the freeway. I drive a 2012 Audi A4 Quattro, can anyone relate or have a possible diagnosis?
