Josiah - enjoyed your video.
I would start with the gears, and have your tune upgraded for them. I am a big Centri fan, but I think a PD blower is much better considering the weight of your truck and what you do with it.

 

Agreed. A Roots/Twinscrew are similar beasts and each has it's own advantage. Either is a better option than the cent for your application IMO. That being said something is better than nothing. So while the vortech isn't "perfect" it can get you going. Later when you come across a deal on a PD blower you can upgrade and sell off the Vortech. You say full bolt-ons, elaborate. Most of the time bolt-ons for a N/A truck don't mean squat for a FI truck.

So just how good of a deal is it becomes the more important question.
