[QUOTE="Powerstroke Man 6.4, post: 1155279, member: 4573"] I run spartan 310 late lock on my J2 dually as a DD and for the past 40,000 miles and i'm not easy on the truck either. Truck got 94,000 miles and almost 5000 hours it even got the EGR coolers on the truck still yet LOL. Truck still got factory blowby. Not studded No puking Injector #4 STFT is outta whack though it sits at -19 at idle now while the others show -0.6-0.0. Truck doesn't throw injector or cylinder codes. I wouldn't be worried on running higher tunes on head bolts just watch your egt's and other temps ie coolant,oil and trans) and don't gun it everywhere you go. I also do oil change and fuel filters every 5-7K. OEM filters [/QUOTE]
