Pismo Beach trip/Grapevine climb

Here I can't seem to download two pictures without issue so here's the first DashBoss view at the top of the Grapevine, probably the toughest climb I'm aware of.

You can see what I'm pulling with my 6.0, estimate this day about 14,000 lbs.
Initially the grade pulled me down to 45 mph at the steepest part but it ran most of the way up at 50-53 mph. I probably was using 3/4 throttle most of the way.

This was at the top of the grade. My boost psi will sometimes go to zero when it really is up around 25-26 psi. Highest delta reading I've every seen between oil and coolant at 23+ degrees, no worries. Intake air temp at 31 degrees difference, things heated up. High oil pressure at almost 2000 psi difference, coasting dropped it way down. Amazing my tranny never exceeded 180 degrees which makes me the most happy about these numbers.
Enjoy the comparison.

Grapevine (cont).

At the base of the Grapevine, entering Castaic. Coolant temps dropped way down, oil a bit slower. Tranny way down of course, and a coasting turbo.

Sure is nice to have live time data when pulling these kinds of grades.

Just curious, what are you using to collect the data. I've wanted to do that on my GMC but don't want to affect the OBD2 and screw up any warranty.
