  1. Tuning: Electronic Engine Management
    2011 WRX. I'm just starting my dive down the modification rabbit hole (keeping in mind I want to avoid voiding my warranty) and would like to subtly add some modifications. I just installed an mbrp catback exhaust and was tossing around the idea of tuning. Here's the question: would a bolt on...
  2. General Maintenance, Troubleshooting & Accidents.
    2004 WRX 2.0 4A I recently put in the Grimmspeed 3 port boost control solenoid(I know it says to get a tune I'm just lazy), never tuned it but my boost would go up to 15psi and drop to 5-10 psi then right back up to 15 and back down to 5-10. Quite annoying, then all of a sudden it won't go over...
  3. Engine Modifications
    So right now I have nothing really done to my car besides a Cobb cold air intake. Installed it and haven’t seen much of a difference besides just the sound of the intake. I plan on getting an axleback exhaust for now but was wondering if I should get a tune for the intake. I know for the...

  6. Engine Performance
    I have a 2018 WRX premium with 49k miles. I was looking into Turbo blankets and header wraps and was wondering if they’re actually effective and give results? And if so is a tune necessary for it? They claim it spoils the turbo quicker, while keeping the engine bay cooler, and heat soak to a...

    Hi everyone, I'm new here. Recently joined the WRX community by finally purchasing a 2015 WRX STi. I noticed when buying the car it has an aftermarket Cobb intake (not sure on the specific model, I'll have to open up the airbox to look for serial numbers), but all I know is that the air intake...

  9. New Member Introductions
    What’s up, all! I’m a newcomer to the forum and have been on here often for research, knowledge soak, and general love for the wrx since high school (2009). I wasn’t raised turning a wrench or around cars, but when I first saw the 2008 wrx, I was in love! Then started my appreciation for the...
  10. Tuning: Electronic Engine Management
    So I have this 2004 Subaru wrx 4EAT I just got a custom catback installed and I’m going to put the Cobb intake tomorrow. Do I go to stage 1+ when I put that Cobb intake? I also have the Cobb access port v3
  11. Engine Performance
    I had a j pipe installed Friday and was told the Cobb 2+ plus v400 would work. However it does not as Cobb updated the tune to work only with the new gesi catted j pipes coming out. So right now I’m stuck with a cel (P0420). And I have no way to get the v361 version as Cobb discontinued it and...
  12. High Altitude Tuning
    I just bought a 2015 STI and have started modding. I have cobb intake and bpv with access port. Im looking into the tomei exhaust. I know the access port helps but I want to dyno tune just to dial it in more. Looking for shops in or around St. Louis what kind of experiences did you have with...
  13. Engine Modifications
    Im new here so bear with me...So I just installed the Grimmspeed stealth box intake on my 2020 wrx. I thought the E-tune would come within a couple of days but they're backed up. Is it ok to drive without a tune if I stay out of boost? I don't really want to reinstall stock intake if I don't...
  14. Engine Modifications
    Hey guys, First off, I'm new to the forum and while I appreciate everything Subie, I'm personally a nissan/VQ enthusiast. A friend likes what I've done to my car, and he's not quite as used to doing performance mods. He's recently jumped on the bandwagon and asked me to help figure out what to...
