This is a "How TO" question for the TST box users. If you had a bone stock 600 except for exhaust and a TST box,... what would you run it on empty? With 15k 5ver? Let's say the majority of you tell me empty I could run 3 hp and 4 tq safely. Can you say when your in high gear bump both up say if your on cruise,. . as in not throttling the truck? What about when your towing,... same example but say getting the load moving and getting to highway speed say you could run 1 or 2 on hp and 2 or 3 on tq,. . could you then bump it to 3hp and 4 tq when towing on cruise to flatten out those hills? I have plans to go with a trans and turbo upgrade soon, but this is for now and have a couple trips planned. Need some insight???
