Hi guys. :) The duramax computer is finally hacked! I can now offer you guys completly custom Duramax computer programming. There are Hundreds of things i can change, and i have several hp ratings that you can choose. THERE IS NO LIMIT TO WHAT i can do with them horsepower wise. But you will break things if you go to HIGH on power ratings of coarse.. But i can do the same power levels that any handheld could ever do, and they are perfectly safe. :) I can change tire sizes, idle speeds, All fuel tables, Glow plugs, Maf tables, ect.. even boost controller stuff.. :)

Mail in pcm programming, and core service is available for them already... Let the fun begin... :)

whats the highest hp you can go with it?

The funny thing is with deisel, it basically boils down to a couple of tables, The pilot and main injection tables, The more fuel you add the more power it makes.

133 hp on the dyno and about 242 ft lbs of torque is the max i would do, And i would tow with it for sure... :)

I could have went higher, but the truck was running low on gas.. :) and all the dead misquitoes where starting to pile up.. lol

pm me with price please.

What motors are you tuning? LB7, LLY or LBZ? All of the above?

I am not sure what you are talking about on breaking things above 133 extra ponies, the Duramax internals are very strong along with the drivetrain. I run 540 ponies just on fuel as my daily driver and I have done so for the last two years. My track HP on nitrous is over 700.

What dyno are you tuning on? What kind of EGT's are you seeing with your tunes?

Transmission stuff is what im talking about. The trans starts to act funny, Mustang dyno is what the numbers are on, As for egts, 1100 or so what what i was seeing. At wot of coarse.

Like i said, you could go higher by all means, But i like keeping stuff safe. Any higher and egts where around 1275 by third gear which was too high for my likings..

As for prices, I was thinking for a spare pcm you get to keep your original and unlimited pcm tuning with all the updates you want for life, " you just pay actual shipping charges" would be $307.70 shipped. That includes the pcm too. If you ship me back your stock pcm, ill refund 100 bucks. :) " so it would only be 200.00 for unlimited tuning"
Or for simple stuff like gear changes and little stuff just $100 dollars if you send me your pcm.

We can do all the lb7's And soon will have the lly and newer finished up.
Thanks guys.
