I got to have a few last night while I watched Makenna; Jennifer took Natalie to bed.
Ah, come on, put the pump in today and let me know.

Deep Breathe...
Let me look into a few things tonight on the fuel supply side. Maybe our cars are just making so much more power than the others that no amount of fuel will be enough.

yes spoke to shad and he doesnt know what to do anymore.its not the pump its not the fpr its not the filter on the pump its very clean.it could be the voltage???????? or leaking manifold???????its so weird as i turn on my blinker the fuel pressure gage drops like 1psi???????voltage again??????? steve how the hell are we going to get to the bottom of this!!!!!!!!!!!!!!!

oh and by the way where should the esm be set at since it was adjusted when i had the blower put in.i heard 2.80 volts as i am now at 2.81 just checked it also the esm would have nothing to do with fuel pressure right????hmmmmmmmmmmmmm since the ecu does not like to see boost maybe something is going on there that we dont know about????

Don't worry, there is a reason for it. It is just the matter of isolating and testing the possibilities. So we have eliminated the most glaring items; now we have to look at the less obvious items.
Tonight I will try and determine the less than obvious possibilities and we can move on from there.
BTW, it is not the end of the world. We can always install a second pump.

But no, it would not have any direct affect on the fuel pressure as it is completely mechanically controlled.

From the ESM Installation Manual:
Special Notes:
1) ESM control Voltage is preset for Honda and Acura automobiles @ 2.93v (NSX, S2000 & 03 CL-S 6-speed) or
2.8v (Accord V6, CL-S, TL-S supercharger kits).
Had Brad and Carl, what is th preset voltage on your ESM??

its at 2.81..... volts alsof MAF sensor (usually found directly after the air filter box), some use a MAP (manifold absolute pressure) sensor or even a combination of both. These sensors are used to determine the amount of air the engine is using so it can deliver the appropriate amount of fuel. In a car with a MAF sensor, when a BOV vents, air is escaping from a closed system. This air has already passed through the MAF sensor and has been measured, and the computer doesn't know that this air never made it to the engine.

Tool462 has had the same problems you guys are having with the CL high boost pulley on his Accord. He had detenation problems in the high rpm range as well.
He tried all of the things you have but larger injectors have seemed to solve his problems, (RC Engineering). He runs rich at low end but fine at high end.
Comptech hasn't pushed the envelope with the boost, so they may run out of answers.
Tool may have a few other ideas, not sure.

OK, here is all I could come with. Outside of the obvious such as looking for kinked lines or damaged wires there might be one thing I could think of. But first, I would seriously check all plumbing including the hook up in the tank. That would be the most obvious if there was some obstruction.
The other thing that might be worth looking into is the PGM-FI relay. There could be a possibility that, even though it is closing, it is still hampering the circuit dropping the voltage a little. It wouldn't be too hard to get a new relay, swap it in and see what occurs.
Eric, you seem to have a good relationship with the dealer so you might want to look into this. Also, pull and replace all supporting fuses as they can limit current. I am hoping that it is this simple and can be a known aspect for now on.

There are three fuses:
ACG S (15A) underhood relay/fuse box
No. 1 Fuel Pump (15A) Driver's under dash fuse box
No. 13 Starter Signal (7.5A) Driver's under dash fuse box
But I would begin with the relay. Although this is a long shot it is certainly worth looking into.

Is what fixed??
We are attempting to isolate Eric's issue. The problem here is that it doesn't involve any of the items included in Comptech's kit; he has replaced every suspect item. So now it is on to factory items.

The scanner wouldn't show anything; did they replace the relay?? If not I'll pick one up and try it out.
However, if there is only 13.0 VDC at the pump that is low. It should be between 13.5 and 14.5 at least. Typically in the low 14 volt range. That would be enough of a drop to see lower than expected pressure values from the pump if others are seeing full voltage.

I finally located the darn relay. I'll check the input and output voltages tomorrow along with generator voltage to see if there is a discepancy. If so I will add in a manual switch bypassing the relay and take it for a test run.
I'll let you know.

Well now Eric claims that he doesn't have the PINGING since the IRMC is disconnected... He also just told me his car feels soooo much faster...
But he just callled me all
to tell me he will 
me if we ever race...
Lord, why me?.....

I just went out and measured the pump voltage at a few places. Here are the results with the car running at idle:
13.6 VDC Before the PGM FI Main Relay
13.6 VDC After the PGM FI Main Relay
12.9 VDC At the pump.
So somewhere there is a drop in voltage. BTW, I measured the voltage at my Amp in the trunk and it was at 14.2 VDC.
Anyway Brad or Carl can measure the voltage at the pump?? Just pull the carpet back and untape the harness. The Black w/yellow is the power feed for the pump.

I may just pick up a relay and rewire the pump feed directly to the battery to insure a good power source. I'll also redo the ground as this is also suspect.

Here is one thing Carl and I have done, that you and Eric have not, (I'm assuming). During the installation of the blower, we replaced the battery grounding cables with better cables.

the stock POS.
New and Improved NAPA... bitchin
Have fun getting to it now that your blower and Icebox are in the way.
I am thinking about the WHOLE grounding kit... I am getting some WHINE through my speakers when I am BOOSTING.

I tapped the power wire, and grounded the meter to the hook above the armrest,
