Turns out it was a bad zener diode, Cut it out, and bam.... 11 psi green bars on the A/F and 1400 - 1500 degrees on the EGT gauge. We added in a front mounted intercooler, and now were running at about 13 psi, with the same egt's, stock inj's and MP logic module. So now were ready for the + 40's and a calibration.
