Believe the LMM is one turbo. It's out now in the 07 NNBS, only 5 more hp than the LBZ.

I don't know for sure and I can't say for sure, but I would doubt that GM would switch to a twin turbo just to get even with Ford. GM's VGT (Variable Geometry Turbo) works better than a twin turbo setup, even one with two different sized turbos. Ford only switched to twin turbo 'cus (I think it's) International Harvester pulled the Navistar contract for the Powerstrokes, or the contract ran out. Anyway, the GM/Isuzu Duramax has all the joint work on the computer controlled turbo and Ford would have had to start from scratch, easy way out: two turbos. GM > Ford IMO

yeah i read on diesel place that it is not a twin turbo..but someone on another site was saying it was. im also very glad chevy/gmc is sticking with the dmax 8 years in a row!

The reason Ford went to a twin turbo setup was to meet the new emissions standards. The 6.4 is still a Navistar/ IH built motor. As you can tell, its workin out real well for them :down:
