bat-talon? mine would hit 10 psi and wouldn't build anymore... would leak air out the bov. There is obviously a restriction in the intake somewhere

That's why I asked him about being able to adjust the BOV(as I haven't used the HKS ones.) Did everything work fine when you first installed this BOV? Also do you plan on running more than 24 or so psi? If not look at the 1gen(eclipse) BOV. It is in the Buschur upgrade path and works great. It is a metal Bov that performs like stock(a little louder, which I am sure you would want) and doesn't ever act up. It is also cheap to boot...

Somthing you can look into after your issues get resolved.

(along with plugs, plug wires, boost controllers, etc.) Lot's and lot's of parts, I had a Re-flash from a person in the dsm community, and still nothing.

It would drive fine, boost fine, then when it got to about 10-13psi range it would fall, sputter and not accelerate any further. The wierd thing is it was strickly boost driven, as in I could hold part throttle 10 or so psi to redline and not have it cut out.

So I had a Super-AFC 2 on the car, and took it to a guy who said it sounded like my tune was bad. After about an hour the car was running GREAT!! (50-trim with supporting mods)

That is all I will say.

I see what you're saying, but you didn't change the tune. You removed (or replaced) one tune with a completely different tuning device, so you don't actually know what the cause was. You just assumed it was a poor tune, and that may have been part of it, but it also could have been the tuning method itself. I didn't even know DSMs could be flashed. What tool does that?

Yeah, someone called me Bat-Talon after diagnosing this problem for the 10th time:

Bat-talon

My crew of saved Gotham City Residents:
someone help please
Boost Leak Sound
3rd gear..6k..no boost..loud vaccum noise
Weird boost problem, please help
boost control problems
Huge problem, please help!
help loud whisle
Help on boost loss issue
Boost Leak... Maybe?
Strange sound, loss of boost, BOV or wastegate?
Boost drop/leak

I've never seen a case where the intake snorkel problem stopped boost at 10psi and leaked out through the BOV. That's not what happens with the intake snorkel problem as you can see in the above threads. It's always the same 3 symptoms:

- At 5500-6000 rpms (any gear), it hits
- Loud whistle that sounds like a huge boost leak (air being sucked through a tiny opening between the hood and snorkel)
- Boost immediately drops down to 10psi or lower (caused by air supply being cut off)

It Sounds Like The Mbc May Be Routed Incorrectly. Make Sure It Is Tee D Off The Bov To The Intake Mani. Not The Ic Piping. I Experienced That A Few Weeks Ago

funny stuff... well apparently my situation was different than your bat-talon syndrome. My car would not build boost past 10psi on wot, it would never hit full boost unless I was in 5th gear and did half throttle pull.

look at wastgate, MBC,BOV .....

every thing you said looks to be a boost leak..what does your boost gauge do?
does is move back and fourth - or is it steady? I would put the boost controller (stock) back on ..and as far as an ignition problem..if you went completely back to stock..that would rule that out as well as the ecu, which would be the last thing I would look at.

Please turn off your CAPS LOCK. No, it does not sound like the MBC is not routed properly - this is not what happens when you get the lines backwards. Also, using the compressor outlet pipe as the pressure source is the proper method anyway.

- Putting the car back to stock doesn't rule out ignition problems nor the ECU. You rule those out by CHANGING the ignition pieces. Putting the car back to stock is the longest path towards ruling out the ignition as the problem. As for the ECU, he could put in a stock map or retune, but going back to stock doesn't help figure that out.

I agree with Warr on this one, seems to be ignition related.. My car had similar problems a while back and it turned out to be a bad plug wire. As soon as I was coming on to full-boost, the car would start a rapid misfiring and just wouldn't move.. Changed out my plug wires and problem solved..

youre right if thats the case!! but how do we know how the mbc is routed? if its directly to the wastegate and STOCK turbo outlet then it is ignition related and swapping the coil packs would be the next step to diagnosis. im curious to see the outcome on this.
