SCT Tune Revision 1.22 OUT!!!!

[SouthTexasDiesel]

It's on their website now, from what I've heard it's a beast when loaded. I'm loading mine up right now.

WARNING: If you have the 6-speed call SCT, the manual trannys require a different file.

Is this tune only for the tuner with the extreme file on it?

[SouthTexasDiesel]

I don't know, but extreme doesn't even begin to describe this tune.

I just went for a 30 mile drive on the highest tune. I had to come home and get a beer.

:burnout HOLY ****

This new tune revision has an insane amount of power. I didn't even get out of first gear before my filter minder was sucked in (stock exhaust new filter). Boost would hit 42-48 psi during every shift, and when in OD it got up to 56.

Noticeable sound difference from the stacks. When I'm gettin on it it's LOUD. Less of a jet sound during idle. And after I let the truck cool down for a few minutes and shut it off, it took the turbos over 15 seconds to stop spooling.

BEST PART!!!!! I always got decent mileage in my truck, but only at 65 mph or less. On the last extreme tune I would consistently get 18-20 mpg at 65 mph, and 14-16 at 75 mph. On the new extreme tune I got 20.5 mpg @ 75mph!!!!

Let us know again when you hand calculate your mileage. Some have said
that the lie-ometer is less accurate with some of the tunes.

I just got it installed and took it for a 25 mile test. It would never shift into od. I was running about 2600 rpms at 65 mph, wtf. Need some suggestions.

I was running the extreme with race shift, job2.

ok I just pulled all the codes.

Thanks mick.

The word from SCT is the Race (firm) shifting does not allow the tranny to go into OD.

So I am going to load the Stock (softer) program.

[mick1955]

That's the pitts! Wonder why?

[Floridayfz450]

I run the race shifting points and mine shifts into OD no problem. This is a pretty badass tune, still think there is way more to go to catch up to spartan though.
