06 wrx overboost
 
So im new to the subaru scene and didnt read up as much as i shouldve. I got a cobb turboback exhaust and a perrian up pipe on it right now, everything else is stock. i was driving in 2nd and shifted into 3rd. the car made a lurching sound. i got a cel and its the p0224. So would i need a MBC and a tune? Or just a tune?

If you do not have a tune with a TBE that is a problem! DP=TUNE. I would probably say not to drive your car or completely stay out of boost while driving until you get it tuned before you do damage to your engine. Which staying out of boost is pretty much impossible IMO.

I would park it, or put the stock exhaust back on till you can tune it. DP with no tune and your going to have a bad time! dont french fry when you suposed to pizza!!

Out of curiosity, why the Perrin up pipe? The stock up pipes on 06+ WRXs are already catless, so it's probably not much of an improvement.

Get some type of Stage 2 tune as soon as possible and you'll be ok. Until then, stay out of boost almost entirely - there's no need to switch your exhaust back to stock if you can will yourself to drive like a grandma for a little while.

Sorry, just noticed the MBC comment - avoid manual boost controllers at all costs! Eventually, you might want a 3 port electronic boost control solenoid, but that will require a professional tune immediately. Your car's ECU is pretty good at controlling boost up to about Stage 2 levels.

I got the up pipe for $50 so I figured why not. So the only way to fix my problem is a tune? And why are mbc's so bad?

Not a bad deal on the up pipe - it'll help your turbo spool a little bit faster, but probably nothing noticeable.

You could get an MBC, but just be aware that you'll often run into PTFB (partial throttle, full boost) situations, so you'll have to constantly monitor everything through a series of gauges and adjust your driving style so you're not mashing the gas all the time. A 3 port EBCS is an extremely popular alternative because it is a "set it and forget it" type of thing (once you are tuned for it).

If your car is trying to produce one thing for said boost, and you're tricking it by giving it a different amount.
What do you think could happen?

Ok so I can make a new thread, but figured since he is allready talking about it I would just ask here.
I have a 2013 COBB stg 2 wrx, invidia DP and COBB catback exhast. and I am running the LWG stg 2 map. and I still overboost in 3rd gear at WOT. any ideas?

Catted or catless invidia dp? I know they make both. If it's catless, there's your problem. Are you throwing cel's?

arewmors 01-01-2014 10:46 AM

Not every car likes OTS maps as well. So even if you're catted with the dp some cars are just not OTS map friendly. You could send a data log to Cobb and see what they say, or get an etune, or even better get a pro-tune. But if you're catless that would be your problem like Adair stated above. I would not recommend catless on the newer gens like ours.

General-Leo 01-01-2014 11:19 AM

Its a catted DP, and the weird thing is I have taken it to a dyno and they ran it saying that they had no issues. The guy even said he was trying to make it over boost.
I'm just going to start another thread so I don't completly jack this one. haha
