Just have a question about a programmer. Which one is the best for the 6.7L. Is Bully Dog a good one to go with?

 

IMO the H&S is the most advanced at this point. Don't think Bullydog has anything for the newer 6.7

 

another thumbs up for the H&S on the new 4th Gens you wont be disappointed.

 

H&S is where its at!! Or, you could wait for the Smarty.

 

So using H&S products, which combination would you use. Also do i need the fuel rail plug or fuel rail shim kit?

 

When I talked with H&S they said that on the newer cummins the fuel rail shim kit is not needed because the relief on them is already higher pressure.

 

I recommend the Black Maxx w/dual pyro! I went Mini Maxx with single pyro and will change it as soon as I can. Of course, my truck has some mods that require the dual pyro and I need a bigger screen.

Once Smarty has perfected their 2011 I will get one.

 

I went one a budget and did the XRT PRO with the full delete for under $1000 with shipping. But many like the digital guages but I am an anolog man myself.

 

I have been wanting to put a tuner on my 2011 3500 4X4 H.O. DRW 3.73 MegaCab, but what about the warranty. A lot of people a putting these tuners but what about the warranty issues. Dealer states a tuner can be detected, even if it is removed when taken to be serviced. Once it is detected there goes the warranty.

 

Dealer is correct....
