I am wondering if it is less of a problem with the DCT, mine is a manual and it's going to use that valve more often than on a DCT due to shift times. Not the first I've heard this happening either, just heard that it was when one had it on full vent. But like I was saying it doesn't matter if I am at full vent, 50/50 or full recirculate, it just changes the amount of time before I throw a code and lose boost.
Could be because it's a manual, but a DTC is basically a computer operated manual that shifts faster than a normal person could. But it doesn't matter even if I shift it manually. Could just a bad batch of solenoids. Seems to be hit or miss on the code. Some of us are good and others are not.

Right however, the DCT shifts faster, MUCH faster than a manual, even when you are in the manual shift mode, so the time in between shifts is milliseconds, in most cases not venting between shifts so no loss in pressure. Whereas a manual would have longer periods between shifts and using the valve more frequently. Even in manual shift mode it's still shifting the same in the sense that even though you are selecting WHEN to shift, you aren't selecting HOW to shift in terms of speed. It still shifts fast.

Sorry forgot to hit on this too, you are right there however, I wonder if that part is the environment in which you are driving? If I am easy on it, it doesn't happen, but any spirited driving I can count on it throwing the code.

Another possibility is altitude. It does make a difference in timing and fuel ratio.

Could be? Who knows at this point, all I know is that I have the solenoid ordered and it is on it's merry way lol

How is this going? Any chance the issue is related to the BOV leaking/defective?
Majority of the aftermarket BOV are "push" type, meaning the valve is pushed open by boost in the intercooler pipe. So fine tuning is needed either by spring preload or stiffer spring swap with a combination with something like a Pierburg to assist with air volume. The "pull" types have the boost pressure holding the valve closed until there is a difference between pressure from the intake manifold and the intercooler pipe. They typically can get away with a softer spring with no adjustments. Push types are popular due to the quick reaction for those who want to vent to atmosphere.

Isn’t this just the lack of the piersburg solenoid, based on others experience?
Majority will have problems without the Pierburg. I never had a problem with mine in both push or pull configuration. I just swapped mine just to have a more reliable solenoid after seeing problems even with the stock BOV.

I haven't had a chance to install it yet, I have it but the weather here has prevented me from actually getting it done. I think I'm going to get it done on my next weekend but we will see. The GFB also has the adjustable spring, I did not adjust it from it's factory settings however, is this something that needs to be addressed?

Is your Corolla 2 door or 4 door? What engine?
It's a 92 wagon, currently has the 4A-FE in it, and I have a blacktop waiting to go in it.

Looks great! Are you running the 6 speed as well? Open ITBs in a 20 valve is glorious.
That's the plan! Open ITBs, once I get that working correctly taking it down to my buddies tune shop and doing a small turbo setup in it. I have been toying with converting it to RWD drive as well, but that may be more than I want to dump into it. It really started off as a "ridiculous" project lol.

I got the car for free, it was running on 3 cyl when I got it. I replaced the valve cover gasket, injectors, spark plugs, master brake cyl, and recently put an all aluminum radiator in it. Straight pipe out to a flowmaster 40 with a tip, XXR 002.5 15x8s full LED conversion, ordered the full headlight units out of Thailand, they are actually glass as well. Quick release NRG woodgrain steering wheel, and one of my favorite parts of the car, the "OOGA" horn lol.

Looks great!
Thank you BTW! Sorry I forgot to actually type that. It is one of my favorite cars I have EVER owned, it's such a blast to drive. It's loud, it's noisy, it's not super comfortable and has power nothing, well power steering but that is it. No ABS, no traction control, but it does have A/C lol.

I bought a beat Saturn wagon with a 5spd, no a/c, power nothing except steering as well, for $300 to teach my girls how to drive standard about 5 years ago. Ended up registering it and driving it for two years until the rear main went. Junk yard gave me $200 for it. I loved that stupid car. It weighed nothing and the 5spd was a refreshing reminder of what it was like back in the day. That is the biggest reason I bought the Forte GT with a 6spd, I missed driving manual so much. This is the only picture I can find of it. I think my wife tried to erase all evidence of us owning it.
