No but it's always a good idea to log it and get it retuned. That's the joy of etunes. They can make some small changes for things like that

Since you indicated that you're hearing this more (in Sept) it might indicate your wastegate can't release enough air (restricted by stk turbo) due to your high boost levels and increased airflow. As the temps get cooler and air is denser the possiblity increases for boost levels that the wastegate simply can't handle. This is especially true if both the exhaust and the intake have been enlarged or pass more air than stock. An SF intake combined with a high flow exhaust can cause this to happen. An easy fix, if you've swapped out the oem air box, is to drop it back in and see if the problem goes away. This is eactly what happended on my 2011 STI. Switched it and problem gone. When the temps warm back up, you can switch back.

Nope it made this noise before the intake. Just haven't swapped my inter cooler yet to see if it is the common issue with the TB hose since that will get replaced with my process west TMIC

Fixed my whistling issue exactly as some have said...

In summary, I started hearing a faint whistle in 3rd gear at about 70% and above throttle after I went Torqued Performance Stage 2 two weeks ago. As the days went by, I would notice the whistling a little louder and more often, and even started hearing it in 2nd gear.

Well, as many have said, when I took off the stock hose, the throttle body side was not tight at all and it pretty much fell off on its own. Instead of taking off the rubber ends of the stock throttle body hose and reinstall, I decided to go ahead and order the Tomioka throttle body hose on ebay (seller name was Fast-Imports).

The install was kind of a pain in the ass because the hose seems a little long in my opinion, but me and a friend were finally able to get it on and muscled the intercooler into place. The car runs great now, and no more annoying whistle!

Do you have to remove the intake manifold to get to the TB end of the hose. I was about to remove my IC then realized I don't think I'll be able to get to the worm clamp on the TB end of the hose, its like way under the intake manifold? Am I approaching this wrong or what.

You should be able to get the tb side off without removing anything else (aside from the tmic). If you are like the rest of us it may even just slip right off when you take the tmic off.

The hard part comes when you are trying to put it back on and make sure it stays on after you put the tmic on because it blocks the only good view of it. But you should be able to rotate the worm clamp so that the screw is facing up and easily reachable with a long screwdriver.

I honestly just tried. Unbolted the two bolts holding the BPV, the two bolts on the left of the TMIC near the turbo, and the 1 bolt on the right side. Started wiggling the TMIC a little. I didn't pull hard by any means but I guess I got worried I wouldn't be able to get the TB end of the hose back on by simply just trying to push it on there after IF I was able to successfully get the TMIC off. So I cut my losses and bolted everything back on. I'm afraid to go any further unless I can have someone more experienced help me in case I get stuck with my TMIC and unable to get it back on. If the stupid intake manifold wasn't entirely in the way it seems like this would be a walk in the park.

You should easily be able to see and loosen the side of the hose that's on the tmic. Then take the tmic all the way off and you will be able to see where the hose mounts to the tb.

I hadn't thought of loosening the hose from the IC end and just leaving the hose on there while taking the IC off and then getting at the TB end of the hose. I'll have to try that when I get more time!

I ended up getting the IC off while leaving the TB/IC hose connected to the TB. I couldn't find any way to access the worm camp with a flat-head nor socket wrench. Tried grabbing a piece of the clamp with pliers to see if I could twist it around so I could access it better - no luck. Tried pulling at the hose to see if it would come off the TB - wouldn't budge. Gave up put the IC back on; almost couldn't get the IC back on but a little smidge of oil around the end of the IC and end of the hose helped it slide right in.

I know it seems that the hose might not be the problem since it seemed to be pretty snug on their and people have said that theirs have come right off with ease. However, I'm inclined to think that it might still be the culprit. I took a short drive to make sure everything ran okay and the car just doesn't pull as hard. I don't know if timing is being pulled and its cutting a bit of my power, but it definitely doesn't pull as hard and seems to hesitate almost. I don't know what else to pin point the issue at. It seems like like maybe a boost leak or idk what anymore.

Its too warm out to get the car to do it's whistle. I asked the dealership if they would do specific-type work, meaning taking the endcaps off both ends of the TB/IC hose, and they said they would but it wouldn't be covered under warranty. It's a little annoying, but I guess if they can't "reproduce" the issue they have nothing to go by to get it covered as warranty work. Frustrating. That's why I tried doing it myself but that seems to have got me nowhere. I'm out of ideas at this point.

Well if the TB side of the hose is that tight its a good sign. What symptoms are you having, the whistle noise and feels like loss of power? Do you have a way to watch your boost and see if you are hitting max boost?

If you are still stock I would keep pressuring the dealership to figure it out. No point in wasting your time.

I can't get the dealer to do anything. I don't know if I could say I feel like I'm not at peak boost and if they could do a boost leak test of what. The car just doesn't feel like it pulls as hard as it did when I first got it.

I have the same issue, e85 protuned with a process west TMIC and forge BPV.

I have had the issues with BOTH my FMIC and my TMIC. I don't see it hurting performance as everything seems to be running perfect, just more of an annoying sound. I checked everything, even replaced the throttle body hose (3 different times with 3 different brands) so i'm 100% sure it's not that. I really think it's something to do with the wastegate.

I did the same. It still makes it but now it's not just a whistle and changes with the waste gate fluctuating. Ill know for sure once I got external wastegate but I think that's it

Just went TP stage 2. Same whistling issue. There doesn't seem to be definitive answer as to what is huh? It's weird that a DP and one more PSI cause the whistle. My boost levels are lower than most based on my altitude. Here are a few logs. Anything look off?

I'm in CO mile high altitude. It is the waste gate or your throttle body hose

I'll check the hose. You talking about removing the end caps?

Read the rest of the thread and you will see what people are talking about for the throttle body hose.

In my case it was the wastegate. Anytime it got above 75% it would make the noise. External fixed that =)

I have the same problem like this guy in the video I get the squeak sound when pulling in a low rpm but with a high rpm there is no squeak, but is there a big problem will happen if I ignore it or what ?


Thanks

didnt think i had an issue, herd the whistle a few times, ordered a venair hose which extremely well and easily, the the OEM hose just fell off the TB and was in 2 pieces haha. now i dont hear the whistle on WOT, just a faint chirp as soon as i get off throttle from WOT, do you guys think that could be the waste gait?

I also did the bullet proof mod and clamped all hoses recommended.
