"Enhance the drivability of the Allison 1000 in the Duramax by reducing the amount of transmission shifting. This easy plug-in module removes the factory speed limiter, has adjustable RPM shift points and reduces quarter mile times by over 3/10’s of a second. A performance tuner like the Duramax Intimidator will be required to take advantage of the adjustable RPM shift points function."

I wonder if we'll see 3/10's of a second like they say.

I might be leary about anything that claims to change the shift patterns of the allison. I think if trained properly with driving after more power is installed the allison will do just fine in my opinion.. But if you try this thing out let us know what you think of it and how it performs.

Now if it controlled the Allison why would you need to add a tuner to make it work? I believe all you can do with it is raise the shift points higher than stock and that's why you need the tuner to raise the RPM range the motor will run.

If you haven't moved the revlimiter, you'll tag it if you move the shifts.

I'll try and test one soon.

Let us Know about it McRat. Im about to do a major tranny upgrade with a big tune and possibly a better box to stack with it.
