Duramax upgrades
 

Just bought an '05 crew dually dmax for hauling and looking to see what upgrades evryone else has done. Already planned on changing the turbo inlet which is very restrictive on lly engines, Magnaflow exhaust, some type of either programmer or flash (considering efi live). My main interest is mileage either pulling or not. My last hauler was a 97 bbc crew dually and although it pulled perfectly, mileage sucked. thanks


Scott, If this thread needs moved, please do.

Jody will definitely chime in on this! He know's a thing or two about these !

Mike,

I have a LMM and did a new air intake, MBRP exhaust and a PPE tune. Helped out alot to get the dpf off (which you don't have to worry about) but now have to put back on to get my tags.

I agree that Jody will far more about this as well as the EFI live.
Good choice on your truck.

Mike --

Since I have an '06 FORD F-350 Crew Cab Dually --- this isn't advice on a GM -- but I will tell you I'm on my second go 'round with the full Gale Banks Big Hoss bundle (also had this on my Dodge) -- I've got the intercooler -- intake -- exhaust from turbo back - their new digital dash which adds "jake brake" style braking.... and I have had ZERO issues with their stuff --- and I tow like a fool. So you might want to just look at their products/bundles to see what they have. They build their stuff "truck tuff" and "safe" for the engine at the same time.

Here Mike,

They can spend your money just as well as here.

This is Definetly the spot to go. Nick is on here as well.

a good tune makes the largest bang for the buck. A simple tow tune picked up Brents truck a bunch in mileage I believe. I used EFI Live to tune his.

Dieselplace.com is a great site for info.

thanks, i have been over at dieselplace a couple times researching stuff already.

I was afraid of that.:willy:

Had an 01, now have an 09. I used an Edge tuner, 5" exhaust, and cold air intake on my last truck and had great results without any funky codes or problems. The 09 is still bone stock but I plan to use the same plan on it.
Tuner, exhaust, intake. Makes these things a LOT more fun to drive. My 01 would get 20-21mpg pretty consistently (2500hd 4x4 with 285s).
