I had an issue with my DCCDPro making my car lean out as the diff would lock. It seems like the DCCDPro is pretty powerful and can cause interference. Make sure that it has its own 12v and ground. That was my issue, once I gave it its own ground and 12v it was just fine. Also check and make sure your connections are all correct (TPS and such).Update:
Well, I guess I am not nearly as close to finishing this project as I thought. I encountered some issues...
First off, my power steering rack to massive dump on me and is pissing ATF pretty well. I am currently looking into doing a 15+ rack conversion, but still undecided.
Second, when I put my Spiider DCCD into manual mode and select full lock, it throws a code for P1307 and P1309. These codes are for the OCVs (AVCS) wiring shorts on both cylinder head banks. This makes absolutely no sense to me and I can't get the codes to pop up any other way. Must be something in the wiring.
Third, SuperPro sway bars/bushings don't fit the OEM clamps in the rear. Probably going to to use the whiteline mounting kit with a slight bit of modification.
Fourth, the ABS sensors that fit my hubs don't match the connectors to the GC wiring harness. Gotta splice those together to work.
Due to all these great events, I still haven't installed my Fluidampr pulley, fixed my test connectors, or started removing A/C components from the car.

Yeah that's my first trouble shoot. Gonna start with giving it it's own ground and test it. If that doesn't work I will try giving it it's own 12V. Heck I might just give it it's own 12V regardless to avoid any potential problems down the road.I had an issue with my DCCDPro making my car lean out as the diff would lock.

I've been reading on the fluidampr pulley (for my 7.3 psd). Not cheap, but all the reviews are good. Interesting how it says it tunes to your mods and continues to thru out your power ban. I'd love to hear alittle more of your impressions of it.
Yeah that tune really changed how the car behaved. The first tuner I took it to gave me the 277 tune and blamed my AVCS not working properly. Shinji saw my results and offered to tune it saying I was leaving lots of power on the table (I knew he was right). Without changing anything, Shinji got me that awesome new power curve. Crazy part is he did it via eTune and the original tune was done on a dyno lol.+30 whp doesn't do that tune justice! With the old peak of 277 at about 7.5k, verses 300 before 6k, must be a different animal entirely.
