9" Installed, but have a problem

Finally got the 9" installed this weekend, and drove the car for the first time today since the swap. I immediatly noticed that the speedometer doesn't work. It's a 4 channel Moser/DLS 9" rearend with 4.11s and has been HPTuned for the gear change. The TCS and ABS work fine so I don't believe it's a problem with the 4 channel connections, but it could be. Does anyone have any ideas?

i'd bet the tune is off. I've messed mine up before on the tune and had it read about 30mph when i was doing 70mph. Granted you have a 4 channel rear and i'm not super familiar with them but i don't think they are tied into the speedo at all.

I had it tuned for 4.10s when the 10 bolt with 3.42s was still installed, don't know if that has anything to do with it. It was still reading with the 10 bolt, but it was showing about 15 mph slow. Hasn't worked right at all with the 9" installed though, and it just threw an SES code this morning.
