I started out initially leaning ProCharger. Did some thinking and decided on Whipple. After more thought, i remain undecided.
I know overall, whipple delivers consistent power increase. You'll get the boost even at low RPMs.
I was then thinking i wont be pulling or hauling too often, and running lower boost at lower rpms might actually be more ideal (less engine wear, tire wear, drivetrain, etc).
Some other differences.. ProChargers tune is easier to install, they have an arrangement setup with HP already to streamline the process. Procharger install is less invasive overall as well. With Whipple, you have to go through HP Tuners and get ecm unlocked, and then upload the Whipple yourself. Part of that process is more involved. Security/immobility relearn requiring a gm dealer (mdi2) tool.
All that being said, since both are good options, I'm stuck at a crossroads... pondering...
