Own an '08 F-350 V-10 and was wondering if anyone has had any luck with performance upgrades. Have owned 3 diesels prior to this V-10 and yes could kick my self for not holding on to the diesel, but am not going to take a $10,000 hit on trading it in. Need some performance upgrades to make it a better tow vehicle. Tow a 29' Four place enclosed currently.
