I'm new to the forums too, and am looking for a tuner. I have an 06 F250 PS. I've seen lots of great talk about SCT custom tunes. I want to have the ability to save fuel when towing or not towing, but will an economy tune work while towing 7k lbs? I've never had a tuner, but it sounds like once an SCT programmer is tuned, that's what you have. Wouldn't it be better to have the ability to change on demand? Is there a tuner that can be changed on demand that has the reputation of SCT that looks after tranny, exhaust temp, EGT, etc.?
Any input will be helpful.
