Installed LPE twin pump setup today, p069e fault now?

Anyone run into P069E fault code after installing a LPE twin fuel pump and fpcm? The car runs great and my fuel pressure issues are finally taken care of.....now i have this check engine light. I'm sure it's something simple, just wondered if anyone else has run into it until I can call LPE on Monday.

The car runs sooooooooo much better now at WOT! Before my pressures would drop to 50-52 psi with a quick stab of the accelerator, now it actually jumps from 58psi to about 65 psi and stayed there until I hit the rev limiter in 4th! It actually took care of some of the minor driveability issues when quickly accelerating from a cruise also. Absolutely awesome setup LPE!!!!!

After searching the forum for my fault code, found out that all of the vehicles with this code had a install issue. It was late by the time I got to the section involving switching all of the wires between connectors, so I thought I better check and make sure i put all of the wires in the correct spot on the new fpcm connector. Rechecked all of my wiring today, and found I put the wire that was supposed to go in pin 17 in pin 33 (one row down right underneath 17) on the new fpcm. I guess thats what I get for rushing.
All is good now, check engine light is off and best of all no fuel pressure drop at WOT!!!
