Normal for ground cable on the battery to get significantly warm/hot. Have the heat exchanger fans/ pump running full time. If anyone can touch the negative cable after idling 15 mins or a decent drive around the block and let me know if the cable is warm.

Short term fuel trim bank one adding +1-4 fuel and bank 2 subtracting the exact opposite - 1-4 percent. Any ideas? Possible 02 sensors switched when installing my RXT clutch?
Deleted the PCV valve and ran breathers on both valve covers. Made sure to cap off the blower and intake side so there wasn't any unmetered air entering the motor. Fuel trims changed quite a bit with bank 1 subtracting fuel and bank 2 adding fuel. Before the change each bank was within 3 points...
