It seems that the stock kegger is setup pretty well for power from about 2,000 - 3,500 RPM. I was looking at the M1 and it moves the HP and torque curve up a little. Which is probably great for bashing around town. Anyone who has a stock 360 knows that they fall on their face at about 4,000 ish RPM.
Personally the reason I drive a truck is to tow my Jeep. So the stock kegger may be best for now. Unless the claims of this new intake is correct, and it makes more HP at 2,000 RPM... that would rock
