I'm looking to sell this AEV EGR Module for my friend. We swapped out his 3.07 gears to 3.73's a while back in his 05 GC and he is now using a different programmer due to the gear swap. It is used, however it is an inline programmer that installs behind the steering column so it's in like new condition. New they go for $296.99 + shipping. If you have the 4 inch Superlift or plan on installing one I'd recommend getting the EGR Module. I have it in my Jeep so I can send it as soon as I receive payment.
