Also,
What was the boost peaking at in a hard pull?.
What were the oil temps getting up to in a hard pull?.
What were the EGT's getting to?.
What were the oil pressures running at idle after fully warmed up?... and while pulling hard?.

It was demandated when I bought it several years ago. I had Running Rough redo the program when we rebuilt after reading about it on this forum. It was running 34-35 lbs boost when we did the program but I can't tell you what EGTs and oil temps were running as I had a driver running it. The driver is generally a pretty decent driver but he may have been using it up to. It is all short haul work so I can keep an eye on how they are driving. I had shimmed the new oil pump when we did the rebuild. It has the variable turbo on it and coolers and everything still attached and I replaced all the sensors when we rebuilt it.
