xCal2 Programming

[ccognetta]

I noticed that is not a setting for the 6lb lower, or any blower pulley on the SCT 4195 Xcal2. Steeda claims the factory performance tune from SCT is rich enough to handle the 6lber.

Queston is that if a tuner makes a custom tune for the truck, will there be a noticable difference in performance vs this SCT out of the box tune? Remember I want a safe tune since I drive it hard daily..

Thanks.

My tunes make a lot more mid range than the canned SCT value files.

Most Ls run a little rich up top, the SF doesn't take that into account as far as I know.

I have the X3. I just installed my 6# lower, and called Dynotune Performance up here in Chesapeake, VA. They told me to bump the timing up 2deg. I did that as well as set the tune to 2% richer... just to play it safe.
They also said stay away from WOT until I get a tune...
I haven't got on it since i put the pulley on.
I should call Dan Desio down @ Pro-Dyno in SC. He's a level IV SCT Tuner.
I'll get back to you if i find out anything.
