I just got my burb two weeks ago. BDS 4 in lift and Nitto trail grapplers and 18" Fuel Boost wheels later I love the look of my ride. However, it seems sluggish from the get go and rather heavy. This is my first lifted vehicle and my question is what should or could I do to give it more low end torque without sacrificing gas mileage. I was recommended a hypertech programmer and intake/outake bolt ons. Any advice would be greatly appreciated.
