My only guess would be to keep the MAP from seeing too much boost and de-fueling.

Is that just your subjective SOTP "WOW" or can you substantiate your assessment with something objective?
Just yankin your crank.

Pretty cool how something so cheap & easy can make such a huge difference. I'd previously considered the 10k, but don't like the idea of always having higher pressures working things harder, and some people report drivability and MPG issues with it. This doesn't seem to increase power or alter stuff much, just gives a momentary power boost to get past the lag which I think should be very safe. I recommend putting an inline fuel filter in to reduce the chance of soot getting to the MAP sensor and maybe messing it up. It might have to be something stronger than the average cheapo clear plastic ones to handle the pressure.

Would also be nice to know what the computer will do with seeing no EBP. May be worth putting a T in the line to connect the EBP sensor. I assume if one still has the EBPV it might be more important to have that sensor working, but I don't know.

Silverhks is gaining momentum as a positive member of FTE.
I ran for a couple if weeks with my old EBP sensor installed and my new one plugged in but zip tied to the fuel bowl. I saw no downside and might go back to that setup if I have to continually clean that tube.

Thanks, Timmy.

If I am reading this correctly, you can no longer monitor EBP? Would it be better to install a T instead of a straight barb? sorry if I missed something.

Your EBP will be read at the MAP sensor so you'll lose the ability to read the true boost unless you have a dedicated gauge. If you install a T fitting the MAP and EBP sensors should read the same since they're both being fed exhaust pressure.

That clicked right when I started reading.

I'll be very interested to see if the overall MPG changes. I drive sporadically and don't track mine.

In theory it shouldn't change other than a small drop from playing with the new found power around town.

Got imploded with the holiday season kicking in. Customers starting earlier every year. Wasnt able to do that run but have managed to rack 37x miles. Filling up this morning for docs purposes here. I DID switch back to stock form due to fear of a hose meltdown, Until i can figure out a more permanent solution(AN fittings/brake lines)..i was in the motor for gp replacements

I'm curious to see the MPG. I think it might go up a hair if one isn't using the extra power too much. Mine seems to shift at slightly lower RPM, but it might be in my head because I was expecting it to.

have you tried adding some of the archoil additive to oil and fuel for the sticking injector(s)?. The 6.0 guys swear by it. you can get it of course on amazon and read the reviews.

I have cold sticking injectors and this mod has helped greatly. When one is stuck the acceleration is really bad, at WOT it takes almost a block to get up to 2kish RPM where it'll suddenly unstick and go. Pretty sure it's when the computer commands the longer injection that it finally pulls the injector free. When two are stuck I could be outrun by a 90 year old using a walker. After the mod: with one stuck I can now accelerate about as well as stock with none stuck and the one that is stuck will unstick much more quickly. The less sticky one will now free up as soon as I press the pedal in Drive, even a god rev in P will do it.

Yes, and it didn't do much if anything at all. I thought it had at first, then discovered that it was just luck of the draw and overnight temps varying the effect. I later discovered that our injectors are nothing like the 6.0 as far as the sticking goes. Ours stick because of wear diminishing the clearance between the armature and injector body and lubricity has little or no effect, it's basically a suction cup type effect that happens. Switching to 5-40 helped, the lighter oil reduces the effectiveness of the 'suction cup'. Running a SuperChips 1705 helped even more, the extended injector pulse width seems to pop them loose much quicker.
