I did some runs with Innovative LM-1 wide band lambda and the fueling was good at 14-16 PSI of boost. First the mixture was 11.4:1 but after leaning it a bit out with the CO screw it showed 11.7:1. Consistent fueling through the revs. The mixture should be between 12:1 and 13:1 for maxium power and a little on the lean side dosn't hurt when I'm running standard intercooler. I must get a new intercooler before I turn the boost up.
