Depends on what your plans are for your engine.

If you are looking at big mods and / or mod that require more fule no it is not the pump for you.

If you are planing on staying basically stock, or only adding a timing device then it is not a bad fit.

Mine gives me 15 at idle and 10 at WOT, this is both without and with my Power Puck installed.

You might also look at the raptor FRRP, I believe it also includes a relocation kit.

Neither of these pumps will support any devices that affect fueling.

I had one on my 01 6 speed. i had the banks ottomind with just the other basic air mods. It worjked just fine. When i sold the truck the new oner put an edge comp on it and it fried the vp44 in 2 days. Now i dont know if it was already on its way out or not but had the DDRP on for 2 years no problems except when he put on the edge

Well I installed mine on Feb 2nd of this year at 239K and it has put out a solid 15 psi at idle and 10 at WOT. This is either empty or pulling my 8,000# 5th up a hill in the Oregon Coast range.
Still at stock location this is a DDRP-02 and came with the cartridge pre filter. The earlier ones had a funky screen that went on the inlet banjo bolt. This may have been part of their issue.

Install is not that difficult, I did mine outside in about 35 degree (dry) weather (Gotta love that block heater) in a little over about 90 minutes.

Remember DDRP is not a high volume pump... For what I know its only a 40 GPH pump... Your going to see heavy pressure falls like a stock pump but with a highier starting point like 18-19 PSI.

Remember DDRP does not address the small stock 6mm ID plumbing nor relocate the lift pump closer to the fuel tank. No pump is designed to suck fuel long distances...

That was true for the DDRP Ver.1 But DDRP-02 is rated at 89 gph and will hold pressure. It is listed as a Stock replacement pump designed to preform better than the Stock pump, but not for Chips that add fueling.

I place a Power Puck on my truck with the DDRP-02 and saw no difference in FP at either idle or WOT, (PP is a timing chip doesn't change the amount of fuel).

That said the PP is currently removed from my truck as I over powered my clutch both loaded and unloaded, back to stock clutch is fine.
Looking for a Valair possible DD organic, or SD Kevlar/Ceramic. It is currently in the stock location and giving 15 psi at idle and 10 at WOT.

Hmmm... Taking note of that...

But your fuel pressure is rather marginal running between 15 and 10 PSI. Just remember you overflow valve on the VP44 is completely closed at 10 PSI and fully open at 14 PSI so as you fuel pressure disappears so does the cooling and lubing ablities of the return fuel.

Just returning that favor...

But thanks for the update information...

I've had one now for about a month. Read my mods, not to much for power. Mainley just fuel economy. I like it! Sure beats replacing the stock LP every year! PSI is steady at 16 and drops to 14 while cruisin!
