I have a claim that a duramax can run 11's on a tranny and live tuning alone. I've heard of low 13's and 12's but 11's I can't see with just those mods by themselves. Can anyone elaborate that really knows these engines?

With a Tranny, efi live tuning, turbo, and twin cp3 pumps, absolutly, but i dont think anyone has done it on a stock turbo and cp3 pump. Maybe a modded cp3 but not a stock one. Some one please correct me if im wrong!

12's with efi and a trans, no problem! Hopefully i'll be able to change that to efi and a clutch to run 12's pretty soon!!!!!!

I didn't think so. There was a claim on the PSD forum about the Duramax being the easiest to get into the 11's. I would agree that it's probably cheaper vs a Cummins at least from my experience. But I was sure you couldn't do it on just tuning and a tranny. I wanted to make sure I had my facts straight first by asking a pro over here! Thanks 05!

I agree there at least has to be a bigger turbo or twins to get into the 11's. IIRC IdahoRob is running a single CPS:gearjamin

There was a thread on the diesel place that BoBo had tuned a LB7 into the 11's, single cp3, and i cant remember what charger, it was a single i know that. It seemed a little unbelieveable to me, but thats what was posted!

Yeah, he's running a Silver Bullet. I've seen the truck run 11's and video taped it doing it to. That was the truck I was refering to in my post.

That's awesome. I swear i'm gonna shoot the next guy to call a duramax a junk engine.
