About 3 weeks back I installed a superchips cortex 3950 and since then my 4X4 hasn't worked. I've been through the loops with superchips, custom write and everything. It's still not working. I'm wondering if it could have just been a coincidence that it happened at the same time. Any suggestions on what to check? Maybe disconnect my battery for a few hours? Any and all suggestions would be great! Thanks guys.

 

Yea, tuned it back to stock, and 4x4 was still gone. That's when I called superchips up and have been waiting for them to fix it (was supposed to be done a few weeks ago...). That's just the thing, I'm not kicking any DTCs at all. It almost has to be them.
