I know you're in the biz so a lot less biased than I am. I tend to find a brand and stick with it. I'm super picky about speakers but not so much on other things. I use to buy Boston Acoustics but I gave up on that once I heard CDT.
My car was on the rollers at DB...dropped off the DW injectors, just in case.
Was in the biz, haha. Everyone had their favorite brands, it's the best to go with whatever you like.
You should give a listen to the higher end eclipse components. I have a feeling they would blow your mind, especially when they get amp'd.
The update is that the car is giving Shane problems and it doesn't seem to be the injectors. He has concerns about both the intake and the fuel system at this point (both of which are new with this build but basically the same as murlo's).
We're in troubleshooting mode and won't know more until he has a second person to help him check a few things.
It's interesting in that Shoot Me Now! sort of way.
I traded a couple emails with Chris at BlaqOPs. Of course he's never heard of this issue...and suggested that it might be the Full Blown hanger. The suction line setup is the only peculiar thing about that and it's hard to imagine how a suction line issue would only affect part-throttle and not WOT.
Do you still have your stock BOV hose? I might need to throw a stock intake on there, depending on what Shane wants to test.

I should still have all my stock intake parts yea.
Shane sent me a brief video showing erratic fuel pressure at a steady load on the dyno (in vacuum). On the BlaqOPs kits only the main Wally 255 is running under vacuum. He suggested that we try swapping it out with a new one as a test. I guess that's a reasonably-priced thing to test.
If necessary I will have BlaqOPs modify my stock hanger for their system (how they normally do it) and ditch the Full Blown hanger. Chris @BlaqOPs says that he has a fuel pressure gauge on his car and it definitely shouldn't be doing this:
That's holding the car at 3000rpms and 5 inches of vacuum in 3rd gear rolling on the dyno. It's no wonder why the fuel trims keep going all over the place from right around 0 STFT to +12.5(max it will do) STFT and back and forth.
So is the second pump just turning on and off there? Maybe try lowering the on point of the second pump or something? But I doubt that is it, since the second pump shouldn't turn on until you hit boost right? There isn't a boost leak on that line to the blaqbox is there?

The second pump should be off within one second of the car dropping below the boost thresh-hold. This is the primary 255 misbehaving, for whatever reason.
It could still be a backflow issue or something with the suction/return line but it seems less probable than a bad Walbro.

I see...nevermind on the leak, that wouldn't turn it on in vacuum still.
Yea I wonder if the return is goofed up...you could have shane pull my wally out of my car and test it that way if you want. Unless he has one there.
Let me know.
Or you could drop in my blaqops setup and try that if you want. Not sure how much actual work that would be but worth a try.
Very generous Dave, thanks. I'm waiting to hear if Shane has a GSS342 on hand. If not then I'll make a couple calls. They are common enough.
Not like I am going to be using mine anytime soon, lol. Not a problem, the car is already up there too
If the pump didn't work and the fuel assembly was the culprit i would say it would be worth a try to swap in my setup quick for testing...maybe not quick but before you spend another 500 on another double pump setup.
Just curious as to why you have it set up to do progressive fueling. We have sold a ton of these kits and the best way is to activate the second pump at a low boost pressure (3-5psi). Another way is just to have them stay on all the time. Im not sure how blaqops is progressively controlling the pumps but that would put more stress on the pump if it had to ramp up and down all the time. Plus it just adds more to the equation for failure. I,m guessing he is using some sort of voltage regulator to do so, but that's just my guess.
