Ask Jody if he turns the decel off when exhaust backpressure is in excess of 60 psi. I’d have to say he doesn’t. Because i know another tuner who was trying to write a decel tune and couldn’t safely do it.
Because brand new factory exhaust valve springs only hold 75 psi. Add in a lot of miles and seat pressure is going to be less.
That’s how you float a valve and ruin a 7.3
If your going to run an exhaust brake it’s highly recomnended to install new valve springs
