I have an 08 6.4 that I put slightly larger than stock tires on (295/65r20). I took it to Ford and had it reflashed for the tires, but I still see a power difference when pulling the 5th wheel up hills. I was hoping to keep this truck stock, but now need just a little more power when towing. My question is: Can I run the towing tune on the SCT ITSX WITHOUT doing exhaust/intake upgrades? I don't want to mess with dpf delete being in CA. I also want to keep the cost as low as possible. My other question is, will I be able to monitor EGT (does 08 6.4 have an exhaust manifold sensor that the ITSX will read)?
