I currently have a BNR Tune. They send the handheld, you scan the trans and engine and send it out, they adjust it for you to get what you want (ECO, RACE, or other). Not 100% on what they adjust, but they do a great job. Definitely feel the power and my dealership has not said a thing about the tune or any other mods. I don't even flash it back to stock when I take my car in.

So is this device just an adjustment to the car's computer? It's not an installed mechanical device?

Correct. They adjust fuel and other things (I am not technical enough to explain that part) to gain more HP and Torque. I have a tune with BNR on E85 (42# Injectors needed) and am estimated at 180-190 hp. I would like to get it dyno'd soon to know for sure.

Correction, 170-180 hp.

But this is also on a "max hp" tune. Jerry adv. when I asked that he is no responsible for anything that happens from it.
