Better than having the decel program #4 of 7 programs and having to push the tuner button a precise number of times.
Makes sense— I’ll have to look at the DP Tuner closer. Does it have a digital display then of the tune it’s on?

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

I’ve went back and did a search on upgrading to heavier valve springs, General information, suppliers, and youtube/ replacement without removing heads. I’m seeing upgraded springs rated for 99 psi and then upgraded springs with the compressed height shortened for 125 psi but they all seem to reference this upgrade as being made for built up motors running high Boost. Is there a trade off or negative aspect to going to the heavier (99 psi) springs with a stock 7.3 / normal boost engine, just for the sake to accommodate the use of the EBPV as an exhaust brake? I guess what I’m getting at is there has to be a reason FORD designed it with the stock 75 psi springs.

No issues running a stronger spring.

No excessive rocker wear or anything.

Shimmed .910’s are the cheapest

Beehives are more geared toward performance engines.

Ford didn’t plan on us running so much boost/exhaust drive pressure.
