2015 Duramax Tuners

DenaliDad · December 26, 2015

Does anyone have any feedback on tuners for these? I got a 2015 Denali Hd and just installed the k&n intake system. I'm not ready to delete yet but was looking at the Superchip flashpack for a boost until I grow a pair and do the full delete/tuner upgrade. Also looking at a FASS lift pump possibly.

Don't think Superchips will work, you will need EFI live to tune the LML. Some of the big tuner guys can do a nondelete tune. Just to me depends on what you want to do with your truck, myself not a fan of the emmison stuff but sometimes you just got to leave well enough alone. See that you are in NE emmison test may not be required, but some states are testing the diesels now.

If you are looking at emissions in tact tuning look up Duramax Tuner or ATP (Adrenaline Truck Performance / Idaho Rob). A lot of good reviews out there for those 2.

On any diesel, the only major thing I have ever intended to do with a tune is shut down the EGR. No parts delete. No need to do that. just shut it down. The downstream stuff doesn't concern me. It is making the engine eat its own feces that I don't care for. From other diesels I have done similar, oil stays much cleaner due to less soot build up, MAP and other sensors last longer and more reliable, turbos tend to have fewer than average problems, EGR valves and coolers are not even used at that point so no need to ever service or replace them. Where folks get into trouble with both reliability and the OEM, is going overboard. I have no interest is pumping up power to impress everyone and I have no real problem with the downstream emissions stuff. I like cleaner exhaust. A EGR shutoff tune alone is the cheapest, effective, beneficial mod anyone can do. Just a simple parameter change that would take some serious code investigation to determine anything had been done. And with all original parts in place, no codes, and no change to any other engine parameters, there is nothing that would pique the interest of a dealership. I have not had any diesel engine OEM ever notice a thing I had done and not had any OEM ever notice or check.
