just went out and turned the clamp to 17.2 psi, the car boost cut around 6000rpm after it held 19....so um yea, like i said this theory can be pretty much thrown out into the garbage. For s**** and giggles i turned to map down to 8.8 psi and not a single change, minus the boost cut going away.
Dada; thanks for making me turn a screw driver at night in the cold....lol

That is really weird. I wonder why you would hold 19 psi if you set it to 17.2 You should be seeing pretty much stock boost levels. It will be interesting to see what the WG duty cycle is once the DH can read the right values. This means that most people should hold around 19 psi with your mods even without the the MAP clamp. But they'll probably boost cut of course. The stock boost control must be really crappy if it can't maintain 15.6 psi but instead allows 19psi. I hope this is not the case cuz when the COBB AP comes out, it will basically use the stock boost control algorithms but just set a different target. Hopefully they'll be able to tune the PID parameters to reduce spike and to reach target better.
I think the map clamp has a bad part in it. What exactly is in the map clamp? Is it simply a potentiometer or is it a circuit? Its not responding to changes and I really don't think the stock boost limit is going to be affected by mods. The stock sensor has the same surface area now as it did then, the pressure won't go up with mods if the ecu cuts at 15.6 psi.
Then I gotta get me a CPE HPFP.
That pump doesnt have the flow of the AT pump available at PG. In fact DaDas racecar didnt show the same characteristics of my pump or the others.
Why would you want to wait.... for a weaker flowing pump.... thats going to cost hella more?
Its like waiting for the standback when the AP is available now.... wait a minute... did I just say that?(boom07)
Hmmmmm...Interesting.

Bro the pumps make so much more power after 6000 its ridiculous. Obviously on that fact alone the ecu is involved. thats why the pumps are so important.. throttle, linked to boost, geez I dont know..
The point is that CPE did not see the same characteristics with their pump as what Laloosh saw with his. Thats because theyre different aftermarket pumps.... different flows. Maybe being a ms6 vs ms3 was involved....
But one thing I feel confident about. the ecu is involved bigtime with this thing. Theres a reason Laloosh is at 19 and Driver311 is friggin running 22 psi with a bc.
funny how the computer controls the throttle as well, and from my data, my throttle opened more after the pump. im not saying that the pump is the reason why i hold 19 psi, just something to think about.
Btw people need to slowly forget about CPE hyped up products, once real reviews come out, they are nothing special....

You should have heard how hard they talked down the PG pump and talked up the cpe pump, when I was deciding whether or not to pre-order a CPE pump. They basically sold me on the fact that they put their pump through rigorous tests and PG didn't. After I thought about it a while, that made me cancel my pre-order.
Don't want a pump anymore until I see more, definitive results. Lets get some data logs in this thread!

Bwahahah.
You'll see dyno charts soon and I'll dig up what I can about the flow characteristics and potential HP#'s. Videos will also be up.
That was CP-E's only marketing point. I'll counter that with guaranteeing every pump I assemble (PG pumps are now essentially the mrlilguyCDFPs) with 100% success rate by driving on it on my personal Mazdaspeed3, with a video online to prove it. I have the time to afford to do so. It inflates costs a bit, but it takes all error and issues out, and presents 100% success rate for these pumps to you guys.
So I went out and tested this theory also. At 4v i hit 19psi and cut. At 3.75v 19psi and no cut. At 3.5v 19psi and no cut. At 3.0v 19psi and no cut. At 2.0v 19psi and no cut. Again who came up with this idea????????????????That was a waste of 30 minutes of my time.
100% success rate? why have I heard so much about bad internals or pumps seizing? and now higher costs?
lol.... I have a feeling that this question is going to have to be answered 100 times in every new discussion about the fuel pumps for awhile.

I don't believe you when you say that turning down your map clamp voltage did not affect your boost. What do you propose is controlling your boost then? THere is no way for the car to regulate the boost if it doesn't know what the boost is. The way your (lack of) theory works, the car would just dial up whatever boost it wanted based on the availability of fuel. Except, again, it doesn't know what it's boost is b/c you've clamped your map. s*** doesn't just happen without an explanation. Think about it b4 replying. Why would sending a different signal to the ecu from the MAP sensor not affect boost if the MAP sensor, as you've stated, is only there for boost cut.
You can't compare anything about the flow characteristics of my or the PG pumps b/c the PG pumps have not been flow tested. There is no data there.. Also, in terms of waiting, AFAIK no one has pumps available right now so you'll be waiting for either pump.
cp-e did not talk down the PG pump. THey advertised their own pump as being rigorously flow tested and 100% guaranteed to work. That's it. Any supposition on your or anyone else's part is due to your own doubt about the PG pump b/c of a lack of flow testing for those pumps. End of story.
This is a lie. PG's pumps have not been flow tested so any talk of comparative flow rates is complete B.S. You have to know what the flow rate is before comparing it to anything.
Here's an interesting point. Think there is any bias on this forum? You PG fanboys are all quiet about the failed internals of the PG pump. Autotek outsourced their internals and quality went to s*** and they failed in pumps yet no one talks about it. Imagine the posts of cp-e hatred if one of theirs had failed.

Let me know what you hear
I'm not here to fight anyone, just stating facts. Quiet? This whole forum knows PG pumps have been seizing. I've got nothing further to discuss until parts are in my hand, furthermore, pump upgrades mailed out with several happy customers.I'm claiming 100% rate because under my watch and installation, I have not seen one kit seize, whether its a VAG car or a Mazda. It is going to stay that way cause I'm testing so much. I had no overhead on PG's pump installation, and I've talked with Ken and Zack about my speculations through observation of other pumps.
Cost is going up because I'm going to guarantee and test every single pump against seizures on my personal car before it is mailed out (was never previously done). That is neither here nor there though. The fact is a great product is about to hit the market, and we're buying a rather large stock of parts.
There is video documentation that going to go up and you'll have no doubt. The time it takes to do all of the testing in front of my eyes, and my eyes only (for I'm the only person I trust when it comes to this stuff) costs money. Time to assemble, time to throw on my personal vehicle, time to drive, gasoline, video, time to upload video, charts, etc, time time time time time.
When parts get in, and pumps get mailed out after testing you'll see several, "OMG! mrlilguyCDFP upgrade FTW!!!!" threads you'll be sick. Feel free to call me anytime.
