I was just driving my car (2011 wrx, catless dp, perrin exhaust, forge bpv, perrin tmic with torqued performance stage 2 tune) and went to pass someone on the freeway at about 60-70% throttle after building boost for a matter of a few milliseconds my car stop pulling and slowed down and i heard a banging sound (i felt as if my tmic had came unbolted and smacked against my hood to try and explain the sound) then milliseconds later my CEl light came on and the car began to pull again but of course i let off completely. The CEL remained on for the rest of my 5 mile drive. I got to work and popped the hood and everything looked and sounded fine so i turned off the car and turned it back on again with the CEL. Any idea what the *&^$ just happened?

Note* I just installed the TMIC yesterday and had sent in two 3rd gear pulls to Eric who then returned with a new map (still stage 2 tuned).

 

stock intercooler? How much boost?

I'd recheck the intercooler hoses first. More than likely one of those popped off. But those intercoolers can blow at the seems. I think Heedz might have had trouble with that on his legacy.

What code? I have a reader but I won't be out that way until Wed.

 

I just just just installed the perrin tmic i bought off heeds...maybe thats the problem

The tune should be 19 but my ap said it boosted 21...

 

could have been over boosting. that sometimes can cause problems like that for a bit

 

So you're over boosting, might be a problem withthe map? Check on your ap what the code is

 

Yeah Heedz got that intercooler to solve a tmic issue. So my guess is something is loose in there or a hose came off.

Have you been retuned with the TMIC?

Pretty common for a house to not get on just right during an install. Those things suck to put on.

 

yeah throw the code up here. will help narrow down the speculation.

 

Cool ill do it on my lunch break.

Idk man i got that hose pretty damn tight...how bad is it to drive on for a few miles? I dont have time to fix it until i get home, about 3 miles...

 

Should be ok just don't go on boost

 

Brenden it's one of two things you either overboosted or the throttle body hose slipped off its a known issue on our car. The throttle body hose is my bet though. You have a CEL right? Check the code on the access port and post what it says.


Just saw you said 21psi that's way too high tell Eric to adjust your WGDC because you are over boosting.

 

P0244 right? That should be the CEL code.

 

Boosting at 22psi is awesome though lol. I missed boosting that high

 

You don't need a lot of boost to make power though. On 91 I boost 17psi and make 292/317. On e85 I boost 16psi and make 351/405. I used to always think more boost always ment more power lol.

Boosting above 20 on pump isn't too safe. Brenden don't go WOT anymore over boosting isn't that great

 

Yeah this is my thought exactly. But he said the hose is all good. I'm a bit worried about the tune at this point. Shouldn't be seeing those boost levels on that tune with those injectors.

 

The stock one sucks. Mine has more play than a 2 dollar hooker.
