higher egt?

I just finished installing a new GT38R and did the ebpv delete. It already has the fx'r at 68 psi at idle, 4 inch exhaust, a DP 6 position Chip, and a afe cold air intake. The Ex runs great but on the upper two chip settings I'm actually getting a little more black smoke and a higher EGT under load than before. It's hitting almost 1300. The red line is hooked up and I'm running a zenner as a Boost fooler on the MAP. Any thoughts?

I couldn't find any exhaust leaks and I'm getting 20 plus psi on the edge gauge. That's the most it can read with the diode. I've often thought that i migh worn causing marginal hpop pressure. could that cause a poor fuel burn?
