New SCT 1.26 tune should be available Tuesday or Wednesday.

I've been running the 1.26 from SCT for about two weeks.
The shifting is about as good as it gets IMHO. Not too hard, and not lazy at all. Very very good.
Power seems to be the same as the 1.22, but all of the roughness and touchiness are all smoothed out.
To sum it up, all I can say is smooth.

It's not a race tune and I don't have any numbers, but the 1.22 has been dynoed at 500RWHP, so this would be the same.
You can squash the gas to the floor from a standing start and be confident that it will shift like a dream at around 3,200 RPM. In town shifting is also moved slightly up the RPM scale from the 1.22
It should do MUCH better at the strip because of this...

Agreed, it's definitely a program that is 100% fine tuned.

We've run 13.6 with this program(no other mods) and dyno'd near 500rwhp. I have customers who have pulled 500+rwhp. Basically this revision is our safe "race" program for daily driving(beating) with excellent mileage. Plenty of fuel left for n20 or an upgraded turbo(s), which is a solid 12 second setup.

Next up, the all out race version. Still needs some refinement, it'll light 'em up at 1/4 throttle. This becomes a slight issue on the back roads.

Eric,

A 12 second F450 sounds like the perfect daily driver to me!
