Of all the upgrades I’ve made this one is my favorite. The braking feel is night and day difference, it’s worth every penny. I recommend installing the super duty P/S pump at the same time you do the vacuum pump delete kit. It makes it slot easier to install the P/S pump with the fan shroud removed. The delete kit doesn’t include two 18 gauge wires or splice connectors which you will need to wire the new vacuum pumps. For the price I think the kid should include these.
