Tunnel Ram Tune
I think your numbers look good for cruise but using 1 O2 sensor can throw you off . Maybe 1 or 2 cylinderss are leaning out ?
I am having my engine dynoed on Nov 6th and plan on trying this out while I am there . This old guy locally actually had W2 dyno headers with individual O2 sensors and says he tunes for low speed as well as WOT.
