Amazing easy to install chip for your 1999-2004 Jeep 4.7 litre V8 Jeep
I ran this for 4 years on my 2002 jeep. Plugs in under dash takes minutes to program engine and reprogram for different uses (towing, power, or better mileage) I had up to 9mpg increases in gas mileage on the highway...well worth the price.
