Cavin: Oh, oh FUCK!

Removing the EGR is one of the "Free Mods" on pre 01 LS1 motors. It does slightly increase HP of the motor. When you remove a heat source you lower intake temps and the motor will increase the power the power it makes This is also the same reasom why people do the coolant bypass in the TB. You are also removing something blocking the air flow in the center of the opening on the intake manifold. More air flow = more power.
The cobra does need a better driver but it gets YANKED and it makes 150 more wheel.
