Stage 1 big boss kit

I highly recommend investing in this kit. I’m already noticing 1/2mpg increase at the pump and a big increase in power and drive ability.

Extra Power

Manifold was easy to install and program. I've noticed a marked increase in power on the power mode and surprisingly an increase in fuel efficiency. I will be trying the economy mode to see how much of an increase in fuel mileage I can gain.
