    Think I'm finally going stage 2

    So now that I have another car in my possession. I finally feel comfortable doing a couple mods to my wrx. My plan is to get an invidia catted dp and possibly an aem intake. I might not do the intake tho because idk how loud it is. My friends Cobb sf is way to loud for my liking but I've read the aem is alot more quiet. Although is Cobb sounds badass
    I'm going to be getting a protune at efi.

    Anyone know if the Cobb accessports guages are accurate or am I better off gettin an a/f gauge too? I already have a spt boost gauge.

    Sometimes tuners recommends for a/f gauge when adding a dp and especially when protuning but not required. I have an aem a/f gauge and was pretty easy to Install. I got the dp with extra o2 bung

    The cobb unit does not read A/F as accurately as a true wideband 02 sensor. If you want to monitor air/fuel then you should get a wideband 02 sensor (AEM makes a quality unit). My cobb doesn't go below 11.1 a/f. When I watch from the COBB to the wb02 sensor it seems reasonably close, but I wouldn't rely on it. Plus, the COBB unit is reading off the stock 02 sensor, which on my car is located behind the cat converter on my down pipe (whereas the uego sensor is pre-cat).

    If you are just thinking wb02 for the tune, then you don't need it. They can use their own set up.

    Yea ill just have to get in contact with them and ask. My buddy has a tune with them and he sends them datalogs every now and then to see how his car is running and they're always quick to reply and look at them.

    I have a cold air intake (not AEM, but Perrin - I would assume they are very similar sounding). You definitely get a louder whooshing sound. You get used to it after a while though and I don't even notice it anymore to be honest.

    Yea I wanna hear it sucking in and all that. But I know I wouldn't be able to deal with the Cobb sf. My buddies is way to loud. Maybe kn drop in filter? I've read about it gunking up the maf sensor but idk I do see people running them.
    I'm sure that's the sound I would want a nice subtle sucking and whoosh that would be barely noticeable

    Does your buddy with the Cobb AF have the airbox to? I just installed Cobb airbox it made it a little quieter not much. But intake is way more efficient because of stock snorkel going into airbox. You probably thought of this already but where you have Cobb AP make sure Protuner can build map for it. AP gauges are ok but not super accurate, I'm going to add AEM boost gauge and A/F wideband sensor and gauge.

    Intakes are not known for adding much in the way of power, as the stock unit flows well up to stage 2 power levels. I'd ask your tuner how much of a difference he thinks it will make, and you should decide if the few additional ponies are worth it. Past stage 2 they become more necessary as the air flow needs increase.

    Intakes (more specifically cold air style) have shown to actually make a nice little bump in power at Stage 1 and Stage 2 levels when tuned. The GD generations didn't really do much with intakes.

    If you want a little more in numbers, go AEM. More sound, go Cobb. FWIW, I had a Cobb SF, no airbox on my 05 STI and the intake and blow off sounds were really loud. I loved it.
