TNT performance on airline specializes in diesels, they can give you plenty of options depending on $$$ you want to spend, ask for Tony

Getting rid of all the hippie parts will do you a whole lot of good. Get that done and go from there.

Gotta get a programmer for that.

I think H&S is the go-to company for Duramax engines. Get an intake and exhaust and be done with it.

Those transmissions don't hold up well with a lot of power added to them. Call Tony and ask what he thinks should be done. Very knowledgeable people over there

Can't you get them set up to run right without trying to push a bunch of extra power out of it?

Yeah, Just turn the programmer down. You won't got as good a mileage as possible by doing so though. On mine, you can run it from stock hp to +350hp. There are 20 different tunes for no EPA stuff, and 10 when you have the EPA stuff on still

EPA junk is what kills mileage and ruins motors so it is best to remove ASAP


Just checked, H&S goes up to +175hp on the 6.6 Duramax. Seems like that is the limit for them. Read lots of forms

Yea thats what I have heard. Drop the ERG and go straight pipes. Tune it for performance and towing. Tuning for just stupid power tears it up.

I'm trying to get 400K miles out of my engine without major repair.

well shite...

Just called TNT. Apparently EPA cracked down on H&S and the like.
Buying a programmer and straight pipes is like buying an AR-15 now.

powertrain warranty runs out.

How do I release the beast in my engine?
1. Programmer
2010 is an LMM easily tuned with EFI Live...can be programmed to your exact modifications and driving style (H&S is/was the only one that released tuning for the LML there may still be some available but that is not what you need)
I know several tuners that can program your LMM with EFI (5 position switchable tuning)
2. Drop to straight pipes and get rid of the earth people bs
The Best EGR delete kit is made by AllSeasonsDiesel I would buy his kit you will need EFI live or you can purchase whatb is called a finger stick to eliminate the Codes that may be thrown(allseason sells them as well)
Depends on your taste for loud exhaust I would go with Corsa...near zero resonance and quiet except when you really get on it...flows as well as any performance exhaust out there too...you can still get a cat delete from most performance shops
3.?
get a Transgo Jr. kit installed(it won't hold 400rwhp daily, but will extend the life of your trans...cheaper than getting a Suncoast stageV transmission installed
Looking for options on economy, towing, power.

Who does this kind of work? What are the negatives?

the tuning(EFI) gives you a 5 position switch position 1 is usually stock but with proper timing and some tweaks that really pep it up position 2 is usually for towing(self explanatory) it gives you added power but keeps your EGT's down in a safe zone when towing heavy loads...3,4&5 is all depending on what you want out of it...some try to tune for mileage on #3, 4 and 5 are usually for hot tunes...but will be set according your preferences and what your truck will handle based on the modifications you've done...you'd be hard pressed to find someone that will give you a race tune or full race tune if you haven't installed gauges(EGT&Boost) or modified your transmission...or put a larger exhaust to keep the EGT's down...you will tear something up if you aren't careful and they don't want to be held responsible...
if 4x4 you will want to get new tie rod ends with tie rod sleeves or they make beefy ones(cognito etc..)that do the same thing.

there is a lot you can do, it's just up to you how far you want to go or how far your wallet will let you...

Let me know if I can answer anymore questions for you...I love talking about this crap...it's a hobby...

Been wanting to tune my new truck, will any mods void the warranty? I am wanting to do exhaust, intake and chip.

So with the economy pick up it basically pays for itself in a year consider i burn about 9k a year in fuel

I had heard that the shut down H&S but didnt know how much truth there was to this. Seems that the Govt got tired of people saying that it was for offroad purposes only.
