sct xcal optional parameter changes?

[BigRobRN]

I was wondering if any of you make changes to the optional parameters using your xcal.

I adjusted my idle from 625 to 675 rpm but didn't adjust anything else.

I adjusted the idle but immediately put it back because while in D and on the brake the truck wanted to crawl forward. I just change to 590 rpm and set it to 3.73

with the custom tunes dont really want to be changing anything about them because they are specifically tuned the way they are for a reason..

my tunes weren't for my tires or gear ratio. I just sent my strategy and got some tunes and threw them in. If you're telling your tuner all this info then yea there is no reason to mess with that stuff as it is already written into the tune.

Very true, unless they know what you have on your truck they can't really tune or for you specifically ... so you gotta let them know everything you have and the tunes will be right on

Just adjust for the proper tire revs/mile and maybe increase shift pressure. I've tried increasing rpms, but it didn't really help it warm up faster and tends to creep more in Drive.

Thanks gents, I'll probably set the idle back to the stock 625 rpm setting.
