Thanks in advance for the help.

Its a 2008 F350 with 148,400 miles. Tuned with Spartan and driven daily on the 150 or 175 tune.

Here's the codes:

P0128 Coolant Temp below Tstat
P0563 System Voltage High
P0625 Generator field terminal low voltage
P1000 System readiness test not complete
U0155 Lost communication w/ instrument panel cluster control module

Recently replaced both batteries and also cleaned the terminals thinking corrosion



Also lost turbo and gauge cluster for a brief moment- Cluster that is- Turbo has been fluctuating. Have been getting manifold absolute pressure- Baro reading low

Just a shot in the dark..........sounds like a dirty or loose connection in a wire harness.
