I cannot take credit for this. I bought a Spearco from a board member (Jack Willson aka turbojack) and he moved the throttlebody on his car to the pressure side and eliminated his idling issues. Hopefully this will help out you guys and girls. He had this setup on a 4.1 T Type with a 3 inch downpipe, BGC headers and a TA49. He reported that the car was STRONG.
