Custom Tune BBP: 2017 GMC Sierra 5.3 SLT 4X4 Update

[Apache32Bravo]

I recently went on a road trip with the family over the holiday from Temecula, California to Antonio Colorado with the Black Bear Performance (BBP) custom tune. Round trip was 2,730 miles of driving with this installed, I'm going to say that hands down, this is the best modification you can do to your vehicle. The shifting is incredible, almost game changing and like a different truck and really pisses you off that GM/Chevy wont make those adjustments factory. Mileage I'm averaging around 17mpg HWY right now and when you need to step on it... this truck MOVES! The pull and response is amazing and really made a difference. All around... totally recommend this. 

I contact BBP and gave them my list of of wants and needs including my mods: 

 

Specific Areas Of Concern: 

 

• Transmission Slippage at slow speeds, get that kick every once in a while.
• Rough Idle.
• Sluggish when you step on it, has a delay to throttle response.
• When you're on the highway and punch it, it has a delay and horrible shifting, all around shifting sucks.
• Spark Plugs are good but has a slow start. 

 

Any Desired Tune Changes:

 

• AFM Delete
• Responsive Throttle. When I touch it I want it to go.
• Smooth Shifting.
• Want truck to no have a lag when I'm on and pull hard. 
• Not looking for a super high performance tuned truck. Most of the driving and style I do is mellow just want a smooth clear ride and power there when I need it.
• Gas Mileage improved.
• Speedometer seems a slight off due to my tires and suspension change recently.

 

Currently my mods are:

 

• BlackBear Performance Tune
• FOX 2.0 Front & Rear (sits perfectly level)
• Method Grid Black Rims
• Toyo Open Country 285/70/17
• N-fab Steps
• Magnaflow Cat-Back
• K&N Filter
• 30" Light-bar with GM-84168423 Mod with active shutters
