Hi ,just installed Packard billet intake and EVO stage 4RWI tune with big injectors and Waste gate. Starts and idles. fine. Seems to rev up normally. Have not test drove due to weather. Noticed code P023D in map tuner as soon as you start it up. You can clear the code but it comes right back . No check engine light just the code stored. Looked in service manual that code seems not to exist. Just wondering if anyone has encountered this , Wondering if this is a map tuner glitch. Waiting for a response from EVO hopefully tomorrow.
