SCT SF3 Questions

I picked it up used SCT SF3 for cheap! It has canned tunes as follows: Trans only, tow 50, tow 65, Performance and finally Street. What are the torque and hp gains? How do I know which tow tune to use when pulling my camper. Which tune, performance or street, will give the best fuel mileage? My 05 F250 6.0. is completely stock. Sorry for the many questions and thanks for any information!

I only use the 65hp tow tune. Performance is a 120hp tune that, if you keep your foot out of it, should give you the best mpg's.

You really need to get you a set of gauges or a monitor to keep an eye on your egt's, tranny temp, and boost. I would highly recommend opening up the exhaust to help get the heat out of the motor or else you stan a good chance of burning something up.

Hope this helps.

I would highly recommend gauges, exhaust, and custom tunes. Typically the highest horsepower tunes also give the best mileage, but are really not suitable for towing.

Thanks guys.........I plan to get gauges and bigger exhaust, but in the mean time I want to get the best fuel mileage. So, if I run a tune and keep my foot light, will I be okay? I'm about to head out for a 1000k road trip (not towing) and I certainly don't want to break something. And if understand, the "performance" tune would be better than the "street" tune?? Thanks again!

Run it perfomance, it will give you the best MPG if you keep your foot out of it, it locks the TC up the most so there is less drivetrain loss.

6.0 with stock injectors dont really get outrageous EGTs, but the perfomance and race tunes advance the timing a little and thats whats not good for motor safety when towing.

For road trips not towing anything, run it in the highest setting you have.

Even with stock intake and exhaust the canned 120hp performance tune should also be safe for stock headbolts too.

As long as you don't put your foot in it and leave it there for more than 10 seconds or so you should be ok. With straight pipe on mine, thats when my EGT's start to hit 1200 or so and I get out of it. Maybe even sooner than that.
