Can someone change my tire size and gear ratio for me pleaseeeeee.....how do i extract my tune from my Xcal 2 so I can upload it to someone that is willing to help??

 

You can do that yourself - User /custom options. Grab your manual - or get it form SCT's site.

The way it works - choose the tune you want, modify the size/gear info, and then refash.

Only the guy who did you tunes can mod them if he's locked them - this is meant to eliminate intellectual property concerns. But for what you want to do, you can do it yourself. IF, for some reason your tuner dude locked down ALL end-user custom option settings, you'll need to contact him.

He is also the guy you need to contact to get your tune files. You can't 'extract' them in any usable form once they are in the unit - they need to reside on your pc.

Good luck

 

Ive tried that already....but the revs per mile doesnt go low enough and the gear ratio doesnt go high enough lol

 

Okay - so you over-modded your truck

Options - contact your existing tuner, give him your new requirements and have him cut you a revised tune. He should have your tunefile on-hand.

If he is not available, then contact any reputable tuner here and buy a new tune. They can or won't mod someone else's tunefiles, even if you had them, AFAIK

 

Is there a minimum that the SCT tuner program will let you go down to for revs per mile....i just got off the phone with my tuner and he said he couldnt go lower then 500 on the revs per mile. He also said that he did have my truck tuned for the 5.13s.

 

I just did some quick back calcs. You would need 40" diameter tires with no load factor to get to 504 revs/mile.

Am I missing something or are you driving Big Foot Jr.?

 

what size tires do you have and what gears are you running?
ha ha no doubt

 

I have 47s lol the revs per mile are 448 and i have 5.13s

 

well damn, yeah, youre right it wont adjust for that. i would contact whoever did your tuning and ask if its something that can be written into the tunes.

 

Okay then - guess you'll have to get your tuner to 'lower' your revs/mile limit or live with it.
