    Default Trouble Code UD026

    i was running my 06 with about a 100hp tune on position 1 at the switch and it threw a couple codes. P0108 high manifold pressure and UD026 which ive never heard of and cannot find anything about it. ive referenced through all the U codes and couldnt find one with another letter after the U. i think all the U codes are communication problems between electrical components. does anyone know what this code is? UD026

    UD026 doesn't even sound like a real DTC. Sorry I don't know about that one.
