Best tuner for Towing

[Utant]

got a 2006 gmc LBZ and would like to get a programmer or box, had the edge on my 2003 and it was great. since they have nothing for the 2006 trucks what is better Diablo, bully dog or hyper pac https://mechanicfaq.com/diesel-tuners-for-6-6-duramax/? what makes the lowest egt's? but good towing power?

I tow a big 5th wheel 15000 lbs!

Not that it’s the best, but Edge does make a tuner for the Lbz. https://edgeproducts.com/shop/diesel-evolution-cts2-ca-edition

Post your location, and find a reputable EFI Live tuner , that’s the only way to go these days
If your towing that heavy you need a tune built specifically for your application other wise your egts will be excessive.

EFI Live from one of the vendors here and get a transgo jr installed

You cant beat a custom tune, but the diablo is a good canned tuner for the lbz. The bullydog runs HOT egt's as I tuned a few for guys because the egt's scared them running empty(1450+ wasn't uncommon on the "tow" setting for the triple dog or whatever they called it). I don't have any experience with the hyper pac, so I don't know how it compares.

But if you can swing it, a small custom tune, egr blocker plate, 4" downpipe back exhaust, and open up the air box inlet and fender opening for the intake(keep the stock intake and box, just do the ppe mods) and you'll be good to go. I know I have a lbz tow tune and it tends to run slightly cooler egt's than stock, keeps engine temps in check, and has the exhaust brake built in.

JoshH built a DSP tune that I had on my LBZ that never got over 1200* pulling a 12000lb fifth wheel and a 5000lb boat behind it.
