Forge BPV question? Green Blue or Yellow Spring? No red?

[specvspeedfreak]

With KN,Test Pipe and ETS 3.25" I had the blue spring + 2 shims, and it holds boost really good. But now it's different because I've got a Piasini reflash, and the old setup on my Forge don't hold as much as it would!
I think with red spring + 1 shim, I've got a little flutter at low boost, but it means that it's the right setup?!

Here some videos:

This reflash is awesome!! I gained 40hp and 60lb/ft with only this reflash!! I dynoed my car after the reflash and with my all mods I gained 55hp and 75lb/ft (280hp on the wheels). The car is totally different now!!

But I couldn't give you the number or link in US because I live in Switzerland!

Here a link who someone did the reflash:

Subbin' because I think the Forge BPV will be my next mod. Is this mod actually SAFER for the turbo than the stock BPV? Or is it more of a performance from holding boost longer gain?

I think the stock valve was being "safer" bleeding off boost that would probably be easier on the turbo than holding higher boost longer. So I guess its performance because you hold boost longer, went from peak 18 to now 20 and hitting 15 and bleeding off to 11psi to holding between 14-15psi. Thats blue with 2 shims on mine.

Oh just another question. How tight did you tighten the top of your BPV and did you use a wrench to tighten it or just your hands?

just hands - wrench will marr it all up

Has anyone had any problems with CELs after installing the Forge BPV? I just installed mine today and I drove around for awhile without the Check Engine Light coming up, but after I got gas the light came up.

Nope...check to make sure your gas cap is on properly.

Yea that's what I first thought it was, but I ensured that it was on right and it is. I just noticed that when I turn off the engine, I can hear a noise coming from somewhere under the intercooler. It sounds almost like a computer's processor when it's working to hard, then a couple of clicks, and then it cuts off. Forget to mention the only other mod I have is the CP-E Nano. I might just have to put all the stock stuff back on and take it to the dealer.

Update: I think I found the problem. The gas cap won't come off.

Uhoh....there is a l o n g thread about this on one of these sites.
Good luck!

I finally got it off after reading a post over in the Mazda 5 section, but the check engine light is still on. Could it just be the ECU?

 

[MicaSp33d]

take out the neg terminal on your battery for a few minutes and put it back in. That should reset the CEL unless theres still a problem. Or you can use a dashhawk to read and clear.

 

[Sinoito]

So I just came back from Advance Auto to read the CEL. It came back "P2187 System too lean at idle speeds." Could it be that a hose came loose when I installed the BPV?

 

[PCspeed3]

i dont mean to thread jack or anything, but is there anyway a stiffer spring could be put in the the stock bpv to eliminate the boost leak?

I've just received my Forge BPV in the mail. I just put the blue spring (no shims) in and I am ready to install it! It didn't come with instructions... does anyone have a link to some install instructions? Thanks!

You dont need instructions, its easy.

Remove intercooler cover.
Remove Stock BPV: 2x10mm bolts 2xhose clamps
Install Forge, reverse of above.
I recommend new screw type clamps for hoses as stock dont clamp well on forge.
Reinstall intercooler cover.

Done! Drink Beer.

 

[DaleNixon]

Yea it was really easy! The clamps are loose but the hoses held tight. I think I'm gonna buy some screw types from Autozone tomorrow.

installed mine today, completed the swap in less than 15 min.

results are pretty solid. seems to build/hold power more effectively.

only 'relevant' comment i would make is that the valve releases pressure so quickly/efficiently compared to the stocker that i experience more engine/drivetrain movement because of the more sudden pressure change. an upgraded motor mount is looking like a must at this point.

 

[DaleNixon]

I didn't notice additional engine movement but I have the Corksport rear MM inserts. What spring did you use, and did you use any shims?
