Hi Guys,

I just purchased a 2007 Navi L with 13,000 miles on it. I am going to use it to pull a 30 foot travel trailer. 8,000 pounds. How do you suggest I upgrade the vehicle to make it a better towing machine? I have already purchased a magnaflow catback system. Any help would be greatly appreciated. CAI? Tuner (what kind and mod?)?

Thanks
