Some things can't be easily e-fixed, even by good hearted knowledgable ppl. You asked for constructive advice... you need a wideband before having any discussion about afrs. You need to get your learn on over at romraider's forums if you're going to start trying to troubleshoot problems with an open source tuned car yourself. Honestly it sounds like you're in over your head a little. Have you asked the tuner, or expressed your concerns? Check your regional forums for local subie owners if you cant diagnose it alone. Best of luck.

Yes I have asked my tuner about it and expressed my concerns. He couldn't come up with anything either.

It was faster before. Then you reflashed. It was slow. You changed it back and it was still slow. Skip looking at the tune and find the boost leak. If your hearing whistling then you have a boost leak. Check all the couplers on your front mount kit starting at the turbo... Could be something stupid. Romraider with learned a, b, c, d will also show you the same thing as learning view would have. Check the out too.

Here is a novel idea....post a datalog. For all you know the VD is wrong and your car is fine. It would be obvious by the datalog.

If you are making 20 PSI by 3700 RPMs something is up. On all the stage 2 GR chassis cars I have tuned peak boost can be had by 3k RPMs FLAT, but that will just increase your TQ, your HP is all in how you taper boost to redline and the timing / avcs you run on the top end.

You and my tuner both agree. Before the EBCS and new tune it would be spooling around 3000. It is spooling much later and it's much harder when it does spool, like there is an on/off switch on the turbo.

2012 WRX's seem to have an issue with the throttlebody to TMIC when boost gets above 20 PSI. I would replace the hose and clamps to one of the aftermarket silcone hoses and v-band clamps. If you haven't already.

Nevermind - I see you are using FMIC instead.

You do not need to post attachments, you need to post a link to the Google Doc files that are PUBLIC for two datalogs. One from each map loaded in the car with as similar conditions as possible, like how you described before concerning VD. Even better, include the data logs you already have also.

And yes, it sounds like you developed a boost leak that you need to find and fix. If you really lost 100 Hp it should not be hard to find as that is a big leak and it will also make you run pig rich [think black smoke out the exhaust].

Nobody does. You use Photobucket or Flickr for photo's and Google Documents for files. Set it to public. I'm starting to see have of your issue already..........

Yea I got a photo bucket account a while back trying to post some pictures however the forum wouldn't allow me to post the link. That's what I meant. And as for the car on the latest revision it is seeing peak boost at about 3400 now and is at about 16psi at 3000.

You should have 18 psi by 3k rpms flat all day long with a 3 port. ****, sometimes I see GR WRXs get 18 psi by about 27-2800 rpms in 3rd. But if your A/F learning doesnt indicate a leak maybe there is something up with your 3 port? Even with the factory BCS peak boost should be had by like 3200-3400 rpms.'

Im not questioning Eric's ability, I am more so saying it sounds like a mechanical issue. If you have a boost leak, your swinging pig rich in boost which may slightly explain the drop in power (but not as large of a change as you are seeing)

This is certainly an odd one...

I was thinking that because the power loss was so close to when I put the EBCS on but I swapped them out last night And it made it much worse. So the grimmspeed is back on. I will try again on uploading the logs when I get time to get back on my computer. Been working some long days lately.

You did change the tune to the one intended for the stock EBCS as well, right?

im not a real trouble shooter guy, but my thoughts would be to remove your inlet of your turbo and see if theres any play/ looseness. your turbo might be on the down side? im not sure im just throwing my ideas please dont yell at me =X

There must be something else going on here. I downloaded your logs and put them on a spread sheet I use, you should have made more power after the tune based on the airflow being higher. Here is a Google Doc link to the Excel file. Airflow is not the only input to making power but still. Timing seemed good also, it just took a lot longer to accelerate.

The shape of the VD plot is exactly what you would expect it to be, just lower. I added 2000# to the weight of your car and it looks like it should be. Have you done any other datalogs? I assume that you did the before and after runs on the same stretch of road, it will make a difference.

Yea I'm pretty sure it's mechanical. Ok so today I drove it about 15 miles and when I came to a stop I saw some white smoke coming out of the tailpipes. As soon as I went to move again it went away. I have also noticed an exhaust smell when I get out of the car right after driving.

Yea I did another one yesterday. HP went up some and torque went up about 55ft/lbs but the torque curve was peaky not flat like usual. I will try to post that one up soon. But yes there are only about 3 roads I can get a pull in on near me so all my logs are paired up by which road I logged them on.

Sounds like it might be time for a compression test and a leak-down test.

Maybe your brakes are "stuck on".
