I thought this had been all resolved sometime ago. The Edlebrock kit is an over priced Roush, poorly engineered, and no the truck kit does not come with the goodies that the Mustang kit does nor does it start out at 5psi. It's 8psi and makes the same power as the Roush...afterall its just a Heaton in a pretty package.

A 150 shot of Nitrious...yeah great idea if you want some pics of your rods laying on the street. Very stupid idea.

To the OP go with a Roush or a Whipple. The Roush can't compete with the Whipple after 8-9psi. The twin screws efficiency really starts to show at this level. But if you just want some boost and nothing to wild you will be very pleased. The Whipple is king in my opinion for its efficiency and its ability to produce the bottom end torque of an Eaton with excellent top end power and fuel efficiency.
