4 wheel and off-road just did a article in the December issue. Air raid cold air intake. Dynomax cat back exhaust and super chip tuner. Baseline of 188 hp and 227 lb-ft of torque at tires. 220 hp and 253 torque at tires after. They useda 02 grand with the 4.7 H.O.

 

Forget all this "cold air intake/superchips/cat back" nonsense. Paint it pink.

 

Cut a hole underneath the gas pedal. You go faster when you can push the gas pedal further. Oh, and "It's A Jeep Thing" stickers is a good place to start.
