Blackbear tuning- 2015 silverado 5.3l


Recommended Posts

Posted

Currently with 6.5" lift 20x10 and 35s i get about 12.5mpg.

When i pull my rzr on my 14' tandem axle steel trailer i get about 8.5mpg.

 

Im reading alot that the blackbear tunes is the best bang for the buck... coming in around 260 plus the core charge.

 

Im looking to improve shift points, throttle responses and get 2 to 4mpg better at minimum.

 

I kind of would like the option to change to economy tune etc but that cant happen with just the blackbear right?

Blackbear Perfromance is the way to go.  I know they can really wake up our trucks.  They did on my 2002 Silverado and technology has changed a ton since then.  Now that these engines are direct fuel injected I'm sure they can do even more. 

 

Not sure if you can get better economy but contact them and see what they say.  To me it is well worth the cost. 

 

I'm getting 15mpg in the 02 and when I tow our 20' enclosed tandem axle trailer it gets knocked down to 7mpg.  But then I only have a 5sp transmission and I do have 3:73 gears.

You aren't going to get much better mpg (especially not 4 mpg), if mpg was a concern you shouldn't have lifted. One thing you can do is get the rear end up where it should be just above the front end based on your sig pic. That will help with aerodynamics, the whole useless cali lean just makes it worse for mpg, towing/hauling alignment and others on the road with your headlights blinding everyone.

How do you figure? My roommate put a canned tune on his dodge with 35s and 20x12s and he most definitely got a good 3 or 4 mpg gain. Im not asking to get 20mpg, im looking for a solid 14 or 15.



Sheesh its not cali lean. It barely sits higher in the front. Its a store bought 6.5" lift.

You will not get the 2 to 4 MPG increase with any tune even if you keep your foot out of it.  If you want to increase fuel mileage I would re-gear the truck first then get the tune to alter shift points.  I have a Blackbear tune and didn't see hardly any improvements on fuel economy. I do however really like the truck much better with the tune with the shift point improvements.

Then how did my roommate see an increase? I dont think he ever hand calculated it, just went off what his dash read.

He also put exhaust and a cai on it. Which i will probably do..

Youre comparing apples and oranges, ram is a whole different truck no need to explain that

 

i have 35" on my 5.3l 6spd with exhaust cai and blackbear tune and get 13 OA mpg, if im easy on the pedal i see 15, and thats with 3.42 gears...

 

if you do want better mpg (econ tune w/ BB) expect to not have the power to tow that trailer and get increased mpg haha

I just installed my BBP Autocal tune and love the responsiveness and shift points.  This is how our trucks should have come stock.   If I stay out of the pedal,  I think it could be possible to save a little on gas, but not much.   By the way, using the Blackbear Autocal, you can swap from Eco to Mod tune in a matter of minutes.

Did your roomie correct for tire size change with the tune also? Could account for MPG change somewhat

Cant go off what the dash says when tuned.  I had a 2012 Duramax tuned and the dash said I was getting 19 MPG but hand calculated was 15 MPG.  Better to hand calculate when tuned.

And that's what i told him. But he never did. I figured since he typed in the tire size it was relatively accurate

We would tune your vehicle via our AutoCal. We can help improve shifting, throttle response, along with HP and TQ gains. With that vehicle it is usually on average 1mpg improvement. It depends on fuel quality, octane, and condition of the vehicle prior to the tune.

I recently emailed them about my 17 Sierra 5.3, its seems like GM changed something and there's nothing BB can do for our crappy 8spd shifting since they say its locked by GM. With that said, what's to be gained on a newer truck like mine? Only mod is MF catback but will add a CAI before and if I do a tune.
