Thanks for reading. One of the main reasons I decided to start this thread was to show people that these are more capable than they get credit for. Unfortunately the EPA cracked down on green diesel engineering’s tune before I decided to buy one. I guess I missed out on that product. Let me know if you want any measurements for the carrier.As someone who also has a Grand with the Diesel option, just wanted to say that I enjoyed reading your posts and look forward to more. Not sure if you are put a tune into your rig but look at Green Diesel Engineering for a tune that helps keep the engine clean, and the extra power is always nice. Keep the info coming, and I might pirate your rear tire carrier design.
