If you have verified there is no boost leak (to cause the boost to stay at 2 psi at 4k rpm, it would be a hole the size of your fist) and there isn't absurd back pressure (no rocks in your pipes), that leaves very little options.
Question, do you always use such low values for the WGDC on the GS? To maintain 25psi s/b somewhere in the neighborhood of 70 (after the spool style of choice). Yours slooooowly gets to ~50 (when you finally hit 18psi), I'm assuming you are giving it the beans for these logs (no TPS to verify). We can see via MAF it takes a while for your car to really start pulling in air.

 

[chetrickerman]

what?? even if something was wrong with the wg system you would still get 11-12 psi

Unless its faulty like a stock BOV.

If it cracks open, it will effect spool

 

[jyamona]

BOV could be stuck open, or maybe the WG arm detached?

I havent self tuned and I am pretty much clueless when it comes to values of data. I do know that there is a massive delay in air intake and boost build up and thats pretty much it lol. The reason I say that is I cant really answer the WGDC being low valued on the GS. My tuner could but he has been sick all week thus my addiction to this thread right now. And, yep. I am WOT in all those logs. Pedal is literally on the floor from 2k rpm to 7-8k rpm.

As a second note... I think it would be very obvious if there was anything wrong with parts on the outside of it. Like a crack on the WGA arm/flapper or it being flopping around as its unattached but it isnt. The cobb BOV could be internally just wide open and letting the pressure out way too early. I pretty much give up. I ordered new a new MFI relay (which I highly doubt was the problem) and I am gonna install my MAP firewall heatshield this weekend and call it a day with this damn problem. I probably will take it down to cobb tuning @ plano and have them work their magic on it. Maybe upgrade to a better WGA instead of the stock one... since I am running EF2. I know on some evo's the stock wga didnt cut it on FP green, it actually slowed down them by 30 whp so I wanna avoid that

Your turbo doesn't have a stock WGA on it, it's MAP's 25psig unit.

You are right, thanks for the correction.

As much as I hate to say it, it sounds like the wastegate flapper might be stuck open somehow. It would bypass exhaust during spool and create a similar scenario to what has been described here. Unfortunately if everything seems fine externally the next step would be to drop the downpipe

 

[Kracka]

I think testing the WGA would be the logical next step.

Oh boy, thats gonna be a pita diy job lol. Thanks a lot for the input Chris.

Like Kracka said... I gotta test the wga i guess or i might just drop it at cobb next week...

 

[Tr6]

Ok. I officially give up. I have way too much shit to deal with right now than to work on my baby... Just not enough time :/. I want to thank everyone for their help. At least this way, I will tell cobb what might the problem be. I will take it down to plano. One of these days....

 

[spikester603]

have you tried driving the car and maybe see what codes you get again??

I still think its a CAT/O2 sensor problem.

My CAT was FUBAR and it just felt like my turbo was coming on late and not much power. Just because they look okay dosn't mean they are okay. My 3 MAF sensors looked fine......LOL

Them codes popped up for a reason buddy.

Multiple missfire code..

O2 sensor fault code...

and p0219 isnt a code you get when you remove the speed limiter (thats rubbish, I dont have that ever and my limiter is gone)

P0219 Indicates the vehicle has been operated in a manner which caused the engine speed to exceed a calibrated limit, is your car an MR/SST?

It will be something simple.

 

[Kracka]

This. Don't give up, we've all been there, it happens! This is your first modded car, when it seems like things are always smooth sailing for some of us it's because we have experience with this stuff, know what to do, know what not to do, have come to expect some issues, and most importantly live local to the shops we use. You'll get your setup squared away and you'll be back to loving your car! Shit happens, don't get discouraged over it, especially something so minor as this.

I drove the car multiple times, including today with the AP checking codes ever time I shut the vehicle off and on. None of the codes came back again and I havent gotten a single CEL since the last time I saw those codes. The codes didnt come back so far.

I cleaned the cats out with 15 psi air, well whatever was there to be cleaned because it wasnt clogged even before I put some air into it. You were still able to see through it with light in either end. As for the o2 sensor, I did run MUT diag, multiple of them to test the sensor if they were operational. MAF sensors work as well, unless the MUT is screwed and the ECU doesnt notice they are fubar.

Multiple misfire pops up and goes away all the time after I got gsc s2 cams. Everything seems great even with the engine light on, no stutter, no nothing. It's just something that comes with after cams. Need a bit more forgiving ECU tweak to fix that.

As for the exceeding limit, yea I do have an Mr Touring - SST.

I know in the end you are right on this, you have been with all the things I needed your help with haha. Not living local to the shops we use aka cobb @ plano is one of the mistakes I have made. Logically speaking, I shouldnt have touch my evo at all haha. Shit happens all the damn time, whether it be minor or major (thankfully nothing major so far). But not being able to 100% enjoy the vehicle and be done with all the tiny little shit just pisses me off now... I get to enjoy the vehicle for a couple of weeks and bam something small... I still love the car, just hate driving it lol. I should be back at Dallas Tuesday around 2 or Wednesday around 2 FOR SURE.

Unfortunately if you don't live near a shop (I'm like 3+ hours from the closest decent Evo shop) you need to be knowledgeable enough to trouble shoot stuff yourself, or have a friend who can. I have a friend who's much better at wrenching on stuff than I am - he also has a badass tool set. I on the other hand, am constantly searching for more knowledge so that I can use it to tell him what I think the issue is and what I want to have him help me with in order to fix it. There are so many particularities with every car, it's not possible for a single shop to be experts on everything, which is why these forums are important!

You are right on all the aspects of what you just said for sure. Forums are very important and I do have access to my dealers workshop, I pull in there and use the lift to work on my own car. That's what I have been doing the past week. I do my own oil changes there as well. So I am covered on the tools part plus I have a few special tools that I got from snap on (like the plastic annoying popit/rivit tool extractor). Evo knowledge wise, I sometimes know a lot more about the evo than the mechanics and dont have any friends who are evo monkeys so I am a bit SOL on that.

I also most of the times have a language barrier happening every now and than and dont really understand how to and/or what to do sometimes but Kracka is always there to help out lol which I appreciate all the time but hey in return I get him some drinks haha.

 

[yuwy]

got a feeling its either the exhaust or WGA. Almost always responsible for late spool. One guy had an issue with late spool and it was a clogged cat. If you can just use a test pipe to check then you'll know once and for all if its a cat problem.

I wish I had a straight test pipe to change it up and test it out :/ No biggie, I will hit up cobb in a 2-3 days so they will figure it all out!

 

[spikester603]

P0219 on an MR is overboost I think? that would defo cause the symptoms that your describing.

I'm not an expert on SST's but that will need to be cleared from the ECU or your car wont boost properly.

Have you tried resetting the ECU? i don't know if this works with all codes??

also if it is overboost, you need to find out what's causing it? leak, cold temps etc... just a thought? i might be barking up the wrong tree here..

hope you get it sorted soon

Appreciate that man, Tuesday I afternoon I will be at Cobb so I am gonna have them look at it. Most likely the WGA is all shot so that will be the first thing to look at. I'll update on what the problem was and how it was fixed for sure.

 

[Tr6]

Alright after a bit of inspection on the turbo at Cobb... The arm that's on the wastegate that holds the actuator is broken here is a picture of it. MAP (Chris Carey) has handled the problem without questions by standing behind his product within a minute after hearing the actual problem which is how every company should do. I really appreciate it all Chris.
