Power valve availability

I'm not having an off idle stumble. I'm just looking to make my power valve work properly. I'm looking to put in a 13.5 and give it a try.

That link that Mopar Sam posted says you can go higher than that if you need to.

One thing to remember is your Main Air Bleed controls when the booster starts.

A bigger MAB will start the booster sooner.

A smaller MAB will start the booster later.

If you are at the end of the T slot and you have not started the booster you can use a bigger MAB if the power valve timing change doesn’t help.

At your vacuum I think it will but you never know.
