I'm no expert, but I've heard tailpipe widebands read lean by about half a point or so? So it might not be quite as bad as the 13.9-14:1 seems to indicate.

Also, wouldn't you lose a little power richening it up (though gain a huge margin of safety)? All I mean is a non-crap tune might not improve the power, though it certainly looks like it would be a good idea.

So do you have headers or what?
