This mod does leave something to be desired. Low End Torque is pretty much non-existent and forces you to always drive up to 5000 RPMs if you want to accelerate. Sound combination is good, but makes me turn my volume a little lower for when I hit VTEC. It would be nice if there was a J series engine with VTEC. Using headphones does improve the experience at least for me and a video of a Stock B16 Covet can be viewed here: https://youtu.be/xAjA_4RpFcE
