I installed the smarty jr 40 hp program to my truck and the preformance is great.eelout I will be towing a trailer a couple thousand miles next week and was wondering which setting do you guy's use when towing?
i started to tell you to program tow in and leave it there that is #2 or 70 hp gives a little more mileage and is smooth, then i seen auto in signature i dislike the auto so much i do not even like to ride as a passenger in one . some others will tune in to help i suggest you put a temp gauge on it before driving it and swap to amsoil synthetic if it does ok on 1 try 2 and watch temp then start saving money for upgrade do not try 3 before upgrade or you will be doing the upgrade sooner than you want
