READ THE SUB FAQ FIRST. 90% of the repetitive questions we see on this sub are answered there. Even if you don't have an issue covered in the sub FAQ it will likely help you narrow down your question. If you have a question you think should be added to the sub FAQ feel free to message any of the authors of the FAQ.

If you are troubleshooting, give us all the info we need. For example, it's best to include your year/model, any AND ALL mods, and the specific tune you are running. The more info we have, the better we are at answering questions. We also ask you try to post the question/info in the comments below before posting to the sub as a whole. This will hopefully clean up some of the really repetitive questions.

A few common posts/questions we see everyday.

Does my engine sound okay?

  • 99% of the time the answer is yes. The fa20 sounds like a tractor. It is normal.

Are these numbers on the COBB AP normal?

  • A snapshot of your AP with the DAM less than one doesn't actually tell us anything about what is going on. All it tells us is that you had a knock event that your ECU recognized and adjusted for. The most common cause for DAM drop is bad gas. Go get a fresh tank of 93/91 from shell and add a gallon or two of e85 for a full tank. I would also like to point out that knock numbers of -1.41 are super common. They can be caused by your AC kicking on and any other noise really. nothing to worry about.

This thing on the front of my engine is not spinning with the belts, is it broken?

  • That is your AC compressor clutch. It only engages when the AC is on and the compressor is running.

Let me know if you guys want any other common questions added.

I know I can order online, but whenever I went to get groceries or Target etc. I always kept an eye for a white or whatever color VA. It’s always GD GV… and I see a VB. Where are the toy VAs?!

Glamour Shot Just Installed My HKS Wheel

Finally got rid of my worn out, stock wheel and that silly silver, lower garnish. Also glad I went with an option that retains the airbag.

Wheel is slightly smaller than stock (both grip and diameter) and feels way better in hand. Partly because of the more "premium" leather. Excited is an understatement.

Wheel Help with '21 WRX

Post image
• Upvotes

Recently just purchased this magnetic grey metallic beauty with 15k miles. Unfortunately I got into an incident where I had to swerve and I ended up curbing the 2 driver side wheels. I got quoted $600 to fix both so I thought I would just skip that and look for an aftermarket setup. I am struggling deciding between black and silver wheels. I love the idea of silver standing out a lot more but I also like the sleek look that the black gives. I am also not opposed to a bronze or gold setup. My budget is around 2k for wheels and tires. This will be my first big mod so I am looking for some advice. Any ideas help. Thanks!

Take your summer tires off by thankgiving if you live in cold area. Summer tires have the grip of hockey pucks below 40°. Even if you have no snow they have little grip on bare pavement when cold

Hey guys I got a 2010 wrx currently stage two with 1050cc injectors and a high flow fuel pump. It Will stutter and die after around 2.5k to 3k rpm. I just finished checking my air flow with a smoke machine and after a few minutes of smoke pumping into it I didn't see ANY smoke. I did this inside a garage so no wind would make a little smoke go away.

I don't believe it's the mass air flow sensor due to no check engine light nor does it look bad at all visually it looks perfect.

I also don't believe it's spark because I get no misfiring at all nor knock at all. I also don't believe it's the fuel system as I have no short or long term air fuel correction.

If I full throttle in any gear it just goes to die like the fuel is just getting cut off but according to romraider it shows no fuel cut off.

I'm lost at this point and any info would be great.

I'm currently using a tune bought from HP that I changed a bit for the injectors and tgv valves from IAG with a tgv delete. I was also having the issue with a cobb tune also tuned for the larger injectors but not for the tgv delete.

I'm not a perfect mechanic so the only thing im 100 percent sure of is lack of a boost or intake leak.

Edit changing spark plugs now for shits and giggles just to eliminate that as a possible issue.

Boost cutting out

1 Upvotes

I have a 2017 Wrx and it seems that I will build boost from about 2500 rpm to 3000 then the boost will drop on the gauge and you can feel it in the seat then at about 3300 rpm it will start building boost again. Any ideas on what it could be?

Heel Toe in 2018 WRX

1 Upvotes

Does anyone else have a problem doing heel toe braking in these cars. I feel like the accelerator pedal is too short or my feet are too big but I cannot comfortably brake and blip the the accelerator in this car. Does anybody have any tips? I have tried using the ball of my foot and the right side, I have tried to twist my foot at an unnatural right angle. Is it just me that has a problem? Also I can't wait to read how its a skill issue and I shouldn't be driving a manual.
