What line pressure modulator valve?
A few years back I ordered a line pressure modulator kit for my F250 from Dfuser. Since I have added stage two DIY injectors along with getting a DP tuner for the truck. Now the truck is shifting pretty hard in anything but my stock setting on the tuner. Instead of sending the tuner back to Jody I was thinking about going back to the stock modulator valve, or something comprable to it. I've lost my stock valve as its been years since doing the install. I still have the install sheet from dfuser, but not sure what valve they sent me as there are three listed on the sheet from Sonnax (perhaps someone else has done this and knows which one they typically send in the kit?).
Since not being able to locate the stocker, does anyone know of an alternative aftermarket valve thats is comprable in pressure to the stocker? When I called a dealer for just the valve, they quoted me around $400 (I think that was for the whole valve body assembly), but I know Sonnax makes replacements for around $50, but I don't know which one to get.
