UICP Blowing Off Throttle Body
Hello evom this is my first actual post on this website. I have already searched this issue with no luck so far so here it goes. A couple of weeks ago I got my evo ix gsr tuned at AMS. The car went in compeletly stock and AMS did all the work and tune. The mods included tbe, fmic, licp, wb255, rc1000s, speed element air filter, WB02, boost gauge, and E85.
The car ran great for the first week I had it. Then I got a check engine light. I went to AMS it turned out being I code from my shaft seals leaking (I want to say it had to do with my idle air control but not really sure). AMS lower the idle and this fixed the check engine light. The car ran great from there but I wanted to fix the leaking seals.
So I went ahead and got the replacement seals from mil spec. AMS installed the seals onto the throttle body. Now my uicp keeps popping off my throttle body at full throttle/boost. No matter how hard I tighten the clamp or what clamp style I use it keeps popping off after going threw a couple pulls at full throttle. I upgraded the clamp to a T-bolt clamp and still the same problem. I am wondering if this has anything to do with my stock uicp or stock diverter valve. Or if anything else that could be causing the problem. Thanks

i had the same problem. i purchased T bolts, sprayed the damn thing with my sisters hairspray and it still popped off.
having the uicp reinstalled, popped off for a few times got the uicp portion that goes on the tb worned out and expanded.
my solution to the problem? i replaced it with ETS UICP and never had the problem again.

Just out of curiosity, did you make sure your BOV was installed correctly? Not doubting the guys at AMS or your tech skills if you replaced your own pipes, etc... But it's a simple mistake that I myself made at one point that could easily be overlooked.

it does work. i had the same problem.
but really if it isn't working now would be as good of time as any to maybe upgrade to the samco hose kit or a set of new pipes!

I don't think they had to remove the bov.. I could be wrong though. I don't know if this helps but I put down 388/405 on 34 psi. I just want it fixed. Like I said I tried the hairspray already maybe I'll look into getting a new uicp. Any other ideas? I think I'm going to bring it up to AMS again.

The problem with the stock air flow system is it routes the valve cover gases back through the MAF (intake pipe) and that puts oil vapor on everything from the LICP, FMIC, and UICP as well as throttle body and intake manifold. If you have not changed or cleaned this out it can cause the stock couplers to become oil soaked and swell, then, no matter how clean you think you get it, it will not stay on. If you want to just change the couplers or attempt to clean yours very thoroughly and re-install it with Max hold hairspray as mentioned above. The key to the hairspray trick working is to get it on and the clamp tightened while the hairspray is still wet and then letting it sit long enough for the hairspray to dry and "set". Properly sized t-bolt clamps are critical also.

time for an upgrade. ETS FTW --> they include nice couplers and tbolts as well. they hold up pretty good and the fitment is great!
