Got the TBE installed and we upgraded our tune
from 08 GSR 91 v106
to 08 GSR 93 v106

Car feels great but wanted your wisdom.

Evo&Son, where did you get your PLX gauges from?

Evo&Son, where did you get your PLX gauges from?

We don't have them installed. A couple years ago we bought an A/F gauge directly from PLX Devices website for our MiniS. When we sold it to buy the Evo, we pulled it and plan on buying their boost gauge to match. We have the white face and are leaning towards pillar mount.

Whats great about PLX is that the brain is a separate box from the display, making the display about 1/2 - 3/4" deep which facilitates mounting. We have only good things to say about PLX Devices, worked great and never any issues.

One cool thing is their new multi gauge which can even be connected to the ECU and you switch displays w/ a remote control. You can select the display design itself.

Looks good!

so I'm not over boosting?

27.7 peak looks fine no knock
drive it and be :dancebanana:

I didn't like them, I had the multi gauge and just recently sold it to someone if FL, so I thought it might have been you.

Just so you know, the remote is wired and you have about 4-6 feet of cable that you have to deal with. And that is from where ever you stick the boxes.

I thought they were a great idea, but having to find a place to put the boxes and then run the extra cable just was a pain, I thought. Plus the multi guage actually looks a bit cheap in picture. The display just isn't very crisp.

Just my 2 cents. Sorry for the hijack.

Not at all - We don't have the multi-gauge, just the stand alone version and its been great and will buy the boost. We plan on mounting the brains inside dash left of steering wheel. Seems to be plenty of room and is easy access.

Looks good to me.

I'm honestly jealous of how you have no knock on a 93 map. I was on a 93 map - was knocking- had to go to 91. I still knocked on the 91 and went custom tune. Your car is baller my friend, baller. Car looks good, it is boosting higher than it's "supposed" to, but consider this - my car is boosting to 28 on stock BOV and I'm not leaking as far as I can tell, so I wouldn't worry about the higher boost, just means more powa!

And HB and Golden know a lot more than me so if they say it's good, then it's good :)

Oh I am sure your stock BOV is leaking....Your turbo is prolly pushing out over 30psi.

Well I don't hear anything and my boost seems to hold well straight up to where it peaks so how would I be able to tell if it was leaking given these conditions?

You can do one of three things:

Search for the posting involving the holding pressure of the stock X valve.

Do a boost leak test

Log your car to see if your load graph mirrors your boost graph. If they are different in a particular location, you are leaking.

Your reading 28psi at whatever sensor you have but your valve is leaking. So in order to reach the same desired psi, the turbo must push more air creating more heat.

Found it for you:

As you can see in the vid, the BOV leaks at 25psi and boost has to drop down to 19-20 before it fully closes again. I crushed mine slightly and it made such a dramatic difference I had to retune my car.

Sorry, we're way off topic here....

I got two thumbs up on my logs so please continue.................... because I peak at 27+ so above 25psi, the BOV should be replaced ?

I'm aware of what the stock X valve is supposed to hold. But the car was tuned just recently to like 27 psi. I think the tuner would have noticed the leak while tuning it. Moreover, my boost curve in logs doesn't show spikes it's clean up and clean down. Is it not possible that my BOV is simply just holding more boost than the average stock BOV for the X?

Unfortunately I don't have the proper tools for a boost leak test atm, likewise because it is a custom tune, I don't have the boost graph. I do however have this graph of my tune showing boost from last month. Does this indicate a leak to you? I have had a few logs where it hits 28. But here is an example of a recent log. In the 27's (below). Mods are below (obviously).

That's because I'm running a stubby antenna and your not :duh:.

Thats cause I like the normal antenna :)

Yes, your car was tuned for 27psi AND your tuner compensated for your leaky BOV. To hit the desired boost level, the turbo has to push more air to compensate for the leak. So your 27psi read at the manifold, is most likely 29-30psi out of the turbo. The additional pressure creates more heat.

If you were to go out and upgrade/crush your bov you will require a retune. The stock valve is only rated to 19-20psi. The fact that it can hold up to 24psi is a very good thing and represents good build quality.

So, to answer your highlighted question above: No, you don't have some magical stock BOV which holds boost better/more than anyone else's out there.

Back on topic:
Op, I would recommend upgrading your BOV when you can afford it. As of now, your logs show that your car is running fine and it isn't going to hurt it to continue to run this way.

My car, back when I was first tuned. ( 91 pump and stock turbo )

Listen carefully when the turbo spools. You can hear an odd flutter type sound as the BOV is forced open then closes again. After the tune I swapped out the BOV for an aftermarket one. My boost went up 2 psi. I turned it back down to where I was tuned to.

In my case, is this my next step? the physical install seems pretty easy but is there more to it than that? I searched around and this one seemed interesting, not that I know the technical differences.

AND if this isn't my next step - what is ?

Hmm. Sounds like I need to get a 100% recirc BOV myself, ask for the maps from my tuner, install it and turn down the boost to compensate. Do you think running like it is currently could be dangerous for DD / Auto X?
