I have the 2011 6.7 did a delete on truck, running the Efi Live tow tune, well it blew head gasket, head was cracked also. going back with new o-ringed head,new Arp 625 head studs and new Fleece Cheetah turbo. My question is what would be a safe tune from Efi live not to blow another head gasket.

Thanks for any input
Chuck
