Diablo Sport Predator mpg improvement?
#11
The MPG tune will gain a bit. It dials back a lot of the torque management as well so there is a power gain as well.
I highly recommend running 89 octane with a Hemi. It is recommended in the owners manual and there have been some engine issues being damaged by unheard detonation in stock form (no tune). I have gained about 1mpg in town using the Predator MPG tune. Getting around 13.5mpg. I only live 3.8 miles from work so much of my driving is in open loop/ cool-rich mode.
I used to live 40 miles from my old job and got the best mpg with the 93 octane tune with 93 fuel.

My last tank of gas with the stock tune got 14.98 mpg which was just about my overall average since purchasing the truck last June. I installed the MPG Booster tune on 2/08 and proceeded to drive 354.2 miles on 23.40 gals of gas (Shell regular unleaded). My mileage increased slightly to 15.14 mpg. Not the stellar results I had hoped for.....but drive-ability was not degraded so hopefully with a couple of more tanks things will improve.
To be fair, I will run two more tankfulls before changing to the 87 Octane performance tune. Then, I will run three tanks with that tune.

Well, things are starting to look up.....Just filled up and my mileage for this tank was 15.76 mpg. Not stellar but definitely an improvement. Especially since I had a little more in-town driving than I usually do. Hope that the next tank improves even more. If it does then I will keep the 87 Performance tune awhile longer. If not, then I plan to purchase a custom tune and see what happens.

Your heading down that rabbit hole fast. You just spent money 200-300 on used programmer. at your mpg gains, that will take a long time to pay off. Now dumping more money into a custom tune, another 200 ish maybe more IDK. And you still wont see gains over 1mpg, if you did, then the factory would be doing it from the get go.
Then that will take even longer to pay off.
Ive done E-fan(200), SC vivid(400), cat back(650), CAI(400), tonneau cover(1000). So ive got in alot of money on mine. and Ive maybe gotten 2.0 -2.5 mpg more on highway.
Ive noticed some nice power gains too, but the mpg savings will take me over the life of the truck to get back. But it also makes your truck unique and your own, so its not all about mpg, its about making it yours.
