we think alike

 

400 HP 450 Torque sound like it's a true upgrade !

 

just 7 months away !

Well, since they missed the mark on the number of gears in the Allison as well as there not being an 8-speed HD trans, I’d be a little weary about the rest of the information.

The GM T1 is for the half tons I thought.

The HP and Torque claims seem to be true.  Only thing that turns me off is that the 6.6 will be direct injection and have the AFM cylinder shutdown game going on just like the 1/2 ton engines.  At least according to GM Authority and other websites.  Both of these features have their own unique problems that can be a problem down the line, but those problems can be reduced if the owner takes preemptive action to deal with them as soon as they get the vehicle in their hands.

I not a fan of the direct injection either. If they put AFM on these there goes the reliability. I was hoping they would keep it just like the 6.0 which is basically bulletproof.

Yeah, I can deal with DI issues. The AFM deal would really cause me to ignore the 6.6
