so it may improve mpg over the 2007-2010 models?

 

Still no HP numbers??

 

it seems to be a big secret with GM, im guessing 370-380hp, and over 700tq...

 

diesel power said they think its going to be around 750 tq but i think thats a llittle much especially if they want to make that on similar programming and hardware there running now but with pierzo injectors you never know. all i know there getting close to cutting metal with those injection pressures. i guess its going to be around 29,000 psi now.

 

they are also using a new injection pump, cp4.2, supposed to be able to deliver twice the amount of fuel of that of a cp3
