I've tried reading through the forum on what settings are recommended when programming with a S67 and while there was a ton of great info, it's seems that there are too many variables for a one size fits all. So based on my signature, would it be okay for me to run sw5 tq1 rp1 vgt3 tm2 Pod ~75 while towing my 5th wheel? It weighs are 10000 loaded. Or would I be better off running sw3 tq2 rp2 tm2 vgt3? If I understand correctly more timing would give me better mpg but advancing the timing too much is not recommended when towing? I'm still trying to figure out how to set the tm vgt rp for towing. Tq I figure with a stock granny should be at 2 with sw1 or sw3 and 1 with sw5.
