I need help with my sct!

[guntersxr]

Ive had my sct xcal for several months now and i love it but i have a few questions. i keep the thing set on extreem performance and i get almost 23mpg on the hiway. this weekend i had a readylift leveling kit and 35" nitto mud grapplers installed. im having trouble locating on the tuner where i can change my tire size. also im making a 13 hour trip to texas (from georgia) pulling a small uhaul. can i leave it on extreem performance or do i need to change it for the trip? thanks in advance. only other performance mod on the truck is straight piped.

if you have qauges just watch your egts and you should be good

You cant change the tire size specifically but you can change revs per mile. Its in the part where it will ask you to enter optional parameters

here is a coversion calculator so you can figure it out

at this time, i have no gauges installed.

[scotty2280]

it should be on the "to do " list, im not sure what you should do i would maybe take it off the extreme setting just to be safe

[guntersxr]

off completely? or on a milder setting?

[choctaw]

Either stock or tow tune if you have it. I don't think you will have any problems as long as you don't rag it too hard.

[Dave]

If you have a tow tune use it or go to stock. A 6x12 uhaul trailer is not that heavy

im actually using the one smaller than that, im only mocing a bedroom suit and my drumset. not much and i wont be racing anyone, lol just driving.

[Dave]

Whos tunes are you running? You should be safe in your extreme tune with that little bit of weight. But if it was me i wouldnt because of the lack of gauges
