CEL Code after Supercharger Install L99
Has anyone out there had any problems after a Maggie Supercharger install
with trouble codes, P3401, P3425, P3441, P3449 ??? I believe these are related to the DOD stuff on an L99. Cyl Deactivation codes I can't find a cure or the problem, any help would be greatly appreciated.  Thank you! |

What is the build date of your L99?
I'm sorry you're having these issues. I don't know what these codes mean, but I'm wondering if the tuning device that was used on your ECM wasn't compatible with your operating system. Some of the newer build date L99's are having this problem. |

DarkNight,
When you installed the supercharger did you change the valley cover? Only the LS3 requires you to do so. The factory valley cover is retained on the L99 to keep the DoD system. If you didn't change the valley cover then you more than likely knocked the DoD plug off of its connector when you slid the blower unit into place. If you reach back there and find the plug disconnected just reattach it. You might need to trim the top of the tab because of there is an excess amount of material on top of it.
