Just to give people a description of Eric's tuning for something other than all out race. I tow with my truck, so I leave the tow tune with firmer shifting and TC lock in my truck all the time. I have towed a little since I have had it, but not to the Beach. For me to get to the beach I take 33-166-101 in central CA.
The climbing of the hills will put a stress on any tow vehicle.
Once you get on 166 it is a climb. 2-3% starting out gradually getting to 7% in about 8-10 miles. The the 6-7% for about 6 miles. After that is is a lot of up downs like driving in the mountains all the way to 101. I think this drive is harder than going north or south on I-5 over the grapevine.
Well the truck did great. Just have a 4" delete, 4" MBRP and Eric's tune. It was a little cooler than normal, low 40's climbing the grades, so that will help make some power. Pulled the filter minder in to about 50% which surprised me.
I tow a 09 3912 Cyclone - 18000 GVWR. Loaded with everything for a 10 day trip. Full water, 1/3 full of both grey tanks and black tank (Wanted to wash them out). No toys in the garage though.
I held the truck at 53-54 by the top of the 7%, hitting the bottom of the 7% at 55. So it didnt drop much. You have a stop sign at the bottom of the 2-3%, so you cant get a huge run at it.
Max Temps (Starting the 2-3% section the truck did not shift into OD)
222 Coolant (Biggest difference was 13 between the 2)
195 Tranny (TC stays locked a lot, which is really nice.)
Boost 40 range (During the climbs it was 35, 40 was with it holding OD climbing the hills following the main grade)
Most of the time the difference between the Oil and Coolant temps were in the 5-6 range. I think the 13 was just caused by the higher RPM. Once crested the top they both went back to the 5-6 difference.
So i am very satisfied with Eric's tow tunes.
