Want to install a GM LS2 12570790 / 19420034 silver blade  90mm throttle body onto a North American LS1 or LS6 car?  Or onto an electronic throttle 2000-2002 GM V8 truck? 

*Notes: For faster idle learning after a calibration re-flash or battery disconnect, you can correct the throttle size in the vehicle calibration. For a 90mm throttle size we use an "ETC Area Scalar" value of 0.0158.
