EGTs & Exh Gas Pressure

[Signature620]

It's a CM871 E (Aus), works locally as a truck and dog (tipper) weighing about 58tonne loaded. It spiked at 41psi but most of the time while under load it was between 32-36. We got 450C peak on the pyro gauge. This is with a 5 degree positive timing shift and he said he was driving it harder than he normally does.
