Intake issue on a 2013 wrx

[Heide264]

No, why contact cobb when it clearly states on their web page that any Subaru 2008+ with an intake need a tune..

COBB Tuning - Subaru SF Intake and SF Airbox Kit

Well, if your car isn't pulling right.. apparently something is amiss? I don't understand why you wouldn't contact Cobb about it given the statement above.

Donkey makes a very good point. Asking if Cobb has seen this in the past would probably be the first logical place to start if you didn't have a wb02. Would have taken less time than reading through this thread, and you may even have learned something useful.

EDIT: My apologies - I thought Cobb's site said that you do not need a tune. Sorry!

All aftermarket intakes for 08+ Subarus require tuning, regardless of manufacturer, in order to ensure the MAF sensor reads properly and the engine operates within safe parameters.

vu_tang... Donkey is suggesting you re-evaluate your statement. It isn't that the "ECU doesn't know what to do with the extra air"

I am having a similar issue with a stuttering / cutout feeling on occasion when accelerating hard on my stock 2013 WRX with 1500 miles. I took into the dealer and they told me that sounds normal and the car ia learning my driving and if it continues to bring it back in. Does this sound right?

Do you have the intake that this thread is concerning? I assume not since you said stock. That is not normal, however. Maybe try another dealer.

No I don't have it, but my thought was maybe he could have had the issue before he installed the intake.

[QUOTE=Fork808;2952151]first of all I am not sure if this is the right spot for this thread, if it isnt please slander me on the internet until the end of time, or till i fix it and put it in the right spot, but if it is the right spot then

So this is whats going on, i just got a new Cobb SF shot ram intake for my 2013 wrx, install went easy but my car does not like the intake at all, at higher RPM's it stutters and runs rough, double checked everything, disconnected the battery during install, so im not sure whats going on. anyone have any ideas? i remember seeing someone saying that if you install anything you should get your ecu tuned to work with it, i didnt think that installing a intake would make my car run that bad ~_~
mind you my other cars i worked on was a 95 GS-T Eclipse and a 2004 wrx which both took the new intakes like champs. so any help to this issue would be great, thanks all![/QUOTe


If you dont have the accessport it wont run right your tuned to your stock air box and now that you opened it up your air fuel is way off.....do you have an air Fuel Gauge in your car? if not it might be a good idea to get one then you will know exactly where you are at at all times.....do it now and see the comparison before and after you flash the accessport. cobb makes a great tune for that intake already flashable its a preloaded basemap you can also download different basemaps of there sight as well the more you do but will not be as accurate or nearly a consistent as throwing it on a dyno if you can find a tuner with accesstuner pro around your area anyywhere it would even be more consistant....but ya your issue is your ecu you just have to tune it to coincide with whatever you do to the car mechanically... and thats with everything .... including something as simple as an intake or exhaust... especially exhaust thats why you hear some subies pop alot on decels because they dont have it tuned....get yourself a boost/vacc gauge and an airfuel ratio gauge so you can monitor what your car is really doing and just remember when you buy them with gauges you get what you pay for and that includes the readings they are going to give you and how accurate they are...

Holy old thread, Batman.

Tune for any mod, simple as that.

Guessing the OP has figured that out by now, and is enjoying at least Stage 1.

Yeaaaaaaaaah...late bump much?

Your information is a bit skewed. Regular A/F gauges are a waste. You don't get anything from a cheapo A/F gauge. You need a Wideband gauge to get any useable info. You do not need to tune for a regular CBE or Axleback. TBE/Downpipe? Most certainly. Intake? Yes...while OTS maps where you follow the map notes are plenty sufficient, you do leave some possible gains on the table as opposed to a full on protune.
