I've been meaning to ask this for awhile. I bought a Bully Dog GT tuner for my Titan several months ago and have wired it in for the gauges. I also used it to remove WOT restriction as well as to change the throttle response profile, but I have not applied any of the full canned tunes to my truck. I know I've also seen people talk about doing a 2* timing advance to their trucks. My question is, is the timing advance included in the bully dog canned tune or would/should I change that separately?

Also, with a timing advance will I need to change fuel? I've been using 87 octane from Costco almost exclusively in my truck. I can buy ethanol free gas from a couple stations in town, but holy $$$$ batman!

The only mod I've done to my truck so far is replacing the factory intake with the Bully Dog RFI.


Thanks for any advice!

If you do a search, there are some threads on here about the bullydog. The timing advance is separate from the canned tune. I would run the ethanol free as much as possible if I could, I get much better mpg with it. Maybe the flex fuels do better with it, but when I find it, I get it. I've had my 15 just on the premium tune (at least that's what I think it is) because my truck wouldn't start on the regular tune (on a side note, I about crapped my pants, because I only had it for about 2 months from brand new and all I could think of was I fried something). They bullydog is just a crutch for me until I buy uprev and headers.

Are you running the timing advance in addition to the premium tune?

Yes I am running the 2° timing advance, WOT, and as I mentioned the premium tune. Truck runs great and get about 15mpg on mostly back roads. I don't have any performance mods yet, with the exception of s&b cai.

Im flex and when I had the BDGT I ran 93 tune with 2* advance. No difference in mpg on any tune the only thing that helped was nonethanol gas. It was a good little tuner but Uprev is better and required with headers once the manifolds fail.

Non Flex 2011 4x4

BDGT premium tune gave me about 15.0 mpg with mixed driving,
regular tune gave me about 14.2-14.6 mpg with mixed driving - both were with stock rims & tires (1 degree advance, I experimented a lot and 1 degree felt best for my truck)

Now with 305/55/20 & Ballistic Jesters with a small lift I get 12.0 - 12.5 mpg with the regular tune.

What it came down to for me was $, the math just worked out best to run regular Costco gas with that tune. Ethanol free gives you by far the best mpg, but the cost is too high (where I live) to justify buying it.
