Does anyone know the volume of the inside of an LSXRT intake in cubic volume. I am having a heck of a time tuning this intake!! Any help would be greatly appriciated. I called Fast and they dont even know. In fact they told me it would not require any tuning but I told them that I have to tune it as I have other mods. I have the tune set up perfect with great fueling all the way around and my fuel trims are going nuts ever since I put the intake on.
