I know that alot of you guys are not happy with our Duramax tunes. the shifting especially. I have been working nights and weekends to refine our tunes. Remember our companies stand is to keep things emissions friendly, so there will be no removal of emissions components.

I have been working on this for the last few months on getting things ready to go and am about to go beta with the LBZ tunes.

I have had this thread on other forums as well.. so here is a recap

Decided to race a co-worker out behind our shop.. He has a 08 LMM DPF deleted, and running a EFI Live tune done by Custom Auto claimed to be around 500hp. My truck dynoed at 440hp


I beat him by a hood length in this vid.. he said he didnt have tow/haul on


last vid

All vids were 2wd non boosted launches

I did have plans on launching in 4wd since i just put sleeves on.. but 5min after we installed them we did a test launch. this was the result....


sheered the end clean off. now my pitman and idler are all jacked up. if i put the truck in 4wd it jerks hard and pulls to the left. epic fail!!


and just cuz here is a random pic i took the other night

 

Nice truck. Are y'all going to have anything else out for cummins? Seems like Bullydog drifted to the gas segment. Not many updates for the diesel much anymore.

 

the GT and PMT have some updated tunes for the cummins. nothing for the older triple dogs tho.

 

Is the triple dog pretty much a dead deal?

 

yes sir. discontinued last year

 

Well dang. I'm old news . Well thanks for your help.

 

are you running the crazy larry tunes?

 

I still got the file on comp and will flip over to it every now and then but I ain't got the hardcore trans. Mines still on borrowed time, but hanging in there.

 

I hate being a member of the borrowed time club

 

Yeah but atleast your trans is smart. Dodge stuck us with the dumbest shifting trans out there.
