Do you have the long-term fuel trims?

Your short-term trims are certainly quite high positive, but ST trims are often less informative..

Based on ST trims alone, I would suggest you have a proper smoke test, NOT one with a cigar and a fluid pump. The brake booster is one area folks miss when doing a smoke test..

your fuel pressure is 1-3 psi high, but I think that might be attributable to your tester.
Your fuel trims are positive which says the DME is adding fuel to the air/fuel ratio, So if it was over-fueling (and I have experienced this), The DME would reduce fuel to the mixture.
