Pulling Hills

We have a hill in the area, probably around 6% that is over 1 mile long. For the last 6 months with my truck loaded (25,000 lbs gross) I can hit this hill at 70 mph, 2000 rpm, 1200F, 17 psi, and roll across the top of it around 62 mph, 1200F, 15psi. Sometimes 3/4 of the way up the hill or as I cross the top I will get a CEL light and it will go back off about 15 miles later.

I do not have a scan gauge, but am guessing that it is running out of oil?

What do you think?

Re: Pulling Hills

I would agree. Do you have the stock 15* HPOP? Have you tried data logging ICP?

I had similar issues and found that I had a weak pump. I bought the Adrenalin and think my problems are solved. Looking forward to Spring and hooking up the trailer and trying things out.

Re: Pulling Hills

My guess would be HPOP but only way to tell would be to data log it.

Or you could spend the money on an adrenaline and ether it will fix it or it wont.
