Be patient, the PCM will eventually figure it out! Well worth it

I have one of these TB's on another of my modified Hemi vehicles. It eventually worked so well that I added one to my other modified Hemi vehicle. Easy install but getting it to play well with the PCM is not. Same problem with the first one too, but it finally came around. It'll take as long as about 50 good run cycles for the PCM to figure out what's going on. You may encounter idle DTC codes (don't reset them yet), surging, hunting RPM, stalling, etc. Once done, it works fantastic. Be patient.
