2004 f350 new turbo, b-proof oil cooler, sct tuner,egr delete
 

New-be. I'm being told to put arp head studs. It's a daily driver w/110,000 miles. Tuner is in tow haul mode. Will tow 11,000lb trailer about 6x a year. Like to put in economy mode? Can I change settings in tuner w/out damaging heads. How much does it cost to put in arp head studs? Roughly?
