A smoke test before/after might be worth it however it probably isn't a one size fits all problem. It might just be as simple as certain models not having their clamps tightened properly. Several people have stated that theirs were loose. Regardless I think it would be the wisest decision for everyone who owns a '15 to at the very minimum check all your clamps. If they are loose, tighten them. If you are worried that stock clamps aren't strong enough or want to prevent it from chewing up the hose, replace them. I would imagine the results are negligible and any difference from stock clamps are just a result of loose clamps in the first place.

The concensus seems to be that installing better clamps will fix boost creep. If anything, loose clamps should cause a boost leak. This is why someone would recommend tightening clamps or running a HWG map. I just don't understand how loose clamps can cause the car to boost creep. Does having loose clamps cause the wastegate to react slower? I don't think they are connected like that. Either the wastegate is too small and cannot bypass enough gas or there is an issue with boost controller; ie the controller can't keep up or is programmed poorly. ??? Very confused |

Nvm. I thought about this a bit more and think I answered my own question.
I think the situation the clamps could address is pressure fluctuations. The sequence : 1. Hitting target boost 2. Sudden and momentary boost leak 3. Boost controller tries to compensate, IE: wastegate closing 4. Overboost / boost creep 5. Repeat from Step 2 Still makes me wonder if a tune without clamps can fix this.

I'm located near a Cobb shop, and many other reputable shops and vendors. Earlier today I was at a shop talking with a customer that had dyno'd at stock and at Cobb stage1 91 and 93. His result was the 91 map was 20hp below the stock map, and the 93 was 20hp over, for a net difference of 40hp. It seems to me that the generic off the shelf maps that are coming out just don't have the detail necessary to make power safely without some risk. And safety is something Cobb has always erred on the side of. My 2015 stage1 tune feels like the jump my bugeye made from stock to stage 2. The cobb map did nothing for me but help with throttle modulation. TL: DR Get a protune or etune from someone good. Clamps didn't fix my issue. Still replace your clamps, you'll thank Danoz in 20k miles. Last edited by schwag wagon; 10-31-2014 at 09:51 PM. |

They say they have
I found two clamps on my turbo inlet piping barely tight everything else seemed fine. I also found every clamp facing in a direction that makes it miserable to get to. I'm going to upgrade clamps in the near future. Sent from my XT907 using NASIOC mobile app |

Yes I know I have to reset the ecu (does it make that much of difference besides the time it takes to learn?), but I have boost jumping between 18-20ish in 3rd. Great...
Putting the intercooler back sucks |

I didn't reset mine and the intercooler was a pain to put back on, especially lining up the throttle body hose to the intercooler after removing it to put on the breeze clamps.
So far I'm showing max boost of 18.5 psi. |

^^Did you put the new clamps under the "rubber collar" on the IC in/out & TB? I put the clamps over them and noticed someone else put the collar on under the new clamps. That shouldn't make a difference.
I already took off the IC again to dbl check the clamps...I guess I'll dbl check the turbo inlet. Last edited by amiexploited; 11-12-2014 at 05:23 PM. |

When reasembling, a light smear of light paraffin oil or vasaline on the inside of the charge pipes allows the pipes to slide back into position very easily. This is direct from the Subaru service and repair manual so its safe to use.

Cheap hairspray works well too. When you first spray/spritz it on it is wet and slippery. When dry it becomes tacky.

So did the reset, did I do it right (pulled batt cable and pressed brakes a few times,that that always worked on my bugeye)? Only had to fix the time/date and the initial on screen agreement (limited). Trip mileage didn't reset, and driver window still had auto up/down.
I let it sit in the on position for a bit, then let it idle for a bit. 44*F 13XXft elevation. Now it max'd at 19 psi, and bounce between 17-19. Is that little bounce normal? It wasn't as bad as before I reset that was almost like 5psi with max 22. Feels good, just not visually I guess with the little fluctuation. |

Thanks for updating this thread with pictures, that I just found, it will make the job easier for sure! As for the trolls, if it causes you any peace, they also troll other threads of NASIOC (hey, they also hate CVT's -- what a surprise!) and the best way to avoid them is using the Ignore feature. Works for me. |

Anybody have any clamps left over so I don't have to buy a 10 pack?

I haven't even received my 2015 yet but after test driving several before putting my payment down, I could tell they had inconsistent boost levels and this makes sense now as to what the problem was. I told the salesman one of them drive better than another and he told me I was imagining it. Haha, and it showed 21-22psi on the max boost gauge.

I'm a little skeptical that the clamps on the pre-turbo intake tract (the third diagram) would even need to be tightened, let alone replaced. That area is under vacuum, not positive pressure, and so unless there is a damaged hose, there should be no problems. My experience on the older high-mount turbo setups is that the equivalent to the red clamp in that pic (on the high-mounts, that's the inlet-to-compressor clamp) barely had to be tightened after doing maintenance, and that in fact, tightening more than "barely" would seriously damage the inlet.
I don't feel qualified to speculate on the efficacy of the post-turbo clamps, because I don't have my WRX in my possession yet. I do find it slightly odd that the OEM clamps were able to damage a hard plastic hose, indicating to me that the clamp in the first picture (the one labeled as the condition of the TB hose after one tightening) was drastically overtightened. |

The tightening of the clamps pre-turbo were to alleviate a number of issues on the Forester XT. You rexy guys never had the problem so it not really necessary but it can't hurt to check them.

I checked my easy to get to clamps awhile ago and they were all tight, couldn't go any tighter with a flathead

Clamps ordered-question
Ordered the clamps (8). I'm not used to working on my car, so a little hesitant to try replacing myself.
I will have my bumper off to change headlights. Will this give me easier access to clamps? My local subaru dealer wouldn't change clamps because they arent factory approved. :P Last edited by Jtpc07; 12-04-2014 at 02:02 PM. |

Anyone who bought the boxes of 10 still have extra clamps? I'll buy them off of you if so.

Danoz how long did this take you to get done? I'm assuming it's something I could get done within a day
