STOCK TUNES SUCK, If your car breaks down and it still has warranty have subaru fix it!
I'll agree the stock tune is not great, but there are not alot of people experiencing broken ringlands who are all stock. 99% of the broken ringland stories are on modded cars ... and many of those were VERY modded.

Some on this forum act like the ringlands are guaranteed to break. Strangely, I'm on my 3rd WRX and have never had a major mechanical failure at all .. and two of those cars were over stage 2.

Am I lucky? Has Baby Jesus smiled upon my car modding endeavors? No .. I simply do proper maintenance, put quality parts in my car, do one mod at a time ensuring all is running good before doing more, and last but not least I do not drive my car like the Duke Boys.

If you buy Chinese knock off parts, install 5 mods at a time, and drive your car like a maniac ... then yes, you will likely have problems.

If most of you saw stock afr's you would cringe and wonder how the car dosnt blow up at wot on stock tune. If you ask me, it's only a matter of time before the stock tune cracks your pistons. Most of you say your car is stock and never have problems. As long as you dont go into full boost under 4k your fine..

And for the above poster who said they got an STi over a WRX for power your wrong. Stock for stock they can dyno the same and or the wrx could be more than the sti. The 265/305 hp is a marketing scheme. Protune for protune they are very close. The 10k more you pay for the sti is for everything BUT more power. In the US HP numbers do not apply wrx vs sti, thanks to the stupid US DOT regulated econo tree hugging tune..

Lol I think it is funny how the STi has a shift light in it and from factory it is set to go off at 4100 rpms.... Could Subaru be saying shift here..

Also from what I herd is the STi's power in the middle of the power band? So anything over 5000 rpms the engine goes flat in power... Correct me if I'm wrong.

It's a turbocharged motor; therefore, the powerband is very broad (e.g. 90% of the power is delivered by 4500rpms, peaks at ~6000rpms, and doesn't fall of much near fuel cut). It's not like an NA motor that relies solely on rpm to generate power which results in a more peaky powerband. A turbo band isn't as exciting has an NA one in terms of how the power continues to build as the rpms climb, but you can be certain the turbo powerband will deliver far more average power which results in quicker acceleration.

Due to the lower air density at elevation, the amount of air that the majority of cars (naturally aspirated) will be able to intake is reduced. Since the car is receiving less air, a fuel that burns faster (lower octane, higher heptane) is used in order to keep the average burn rate in proportion. If a higher octane is used on an NA motor at altitude, the burn rate is slowed enough to decrease power due to incomplete combustion (decrease it more, in addition to the decrease in power due to less air in the first place).

Actually very few people, or none, have pointed to a stock wrx post 2008 with failed ring lands. Andecdotes , which is all we have, to me suggest that STI fails much more often in stock form than the wrx. Are the AFR so bad on stock wrx vs known lean on STI? It would be interesting to hear from stock wrx failures. since presumably , at least post 2009, many more wrxs are sold vs STIs one should "hear" about more wrx ringland failures, but i've noticed the failed ringland threads seemingly always entail an STI sometimes in stock form. I'm thinking of ordering a '13 and for this reason (well, speculation) I'm leaning towards wrx.

I have a 2012 WRX at stock, was talking to a few mechanic buddies of mine and some guys that do AUTOx. From their experience with WRX and their friends they've only failed with mods (not saying that's the only way you'll fail)

However I was told that the Stock A/F ratio is a little lean I looked it up and I find anywhere from 13.7 to 14.7 Air to 1 fuel.

If you go stage 1 with the Access port just by changing your fuel mapping it should take you down to 11.2 or 11.1, from what I've read.

The richer fuel mixture can help prevent knock and the other issues. I'm still under warranty, I will not flash or change anything until I'm out of warranty, I don't want to risk blowing anything and not having them cover it. Once its out, I'll probably go to Stage 1 for the richer fuel mix even if it's just better for the car. I'm not doing AutoX on it and I drive it pretty straight.

You're half right, it's ~13s at tip-in, piggy rich further in the powerband. If it was 13s throughout the powerband they'd all explode first trip to redline. Aftermarket em addresses the tip in issue and leans it out approaching redline.

That's leaner than I thought. Other graphs I had seen showed it being less dramatic, and being richer (low 10's) approaching redline.

I have a 2010 STi with zero issues and already at 57k miles. 30k of those miles on upgraded turbo with supporting mods and 370whp on E85

That reading is clearly not from a wideband o2, therefore the AFRs on that graph are garbage.

Where would those figures come from? If it's a VD, I doubt it's a tailpipe sniffer.
Factory oxy sensor?

Yes. Hence why it flatlines at 11.1 cause it can't read below that.

torqued performance stage 2 flatlines at 11.1 before 3000 rpms..pretty much as soon as the boost starts climbing. The wideband shows 10.7-10.9

Just read every single post in this thread. I don't want to lose this information in case I ever need to recall it(maybe Subaru should recall their engines). Judging by the amount of views, it sounds like all of us are at least a bit worried.

At this point my 2012 WRX is 100% stock with an extended warranty. Just touched 14,000 miles today.

I'd say tune it as soon as possible so you are not running it lean while under warranty. Then you have done minor damage already so when you do mod it will not be beat up already. Just imho

a lot of people spreading this around dont even own the car! from what I've seen this was more of a issue with the "08" STI. I have not read about very many 3rd gen WRX's having this problem. I have however read a lot of comments by people "who have never owned one" spread this around. I dont even pay attention to it no more. I havent had any problems with my 12 and dont expect to. I take care of it, I know how to mod correctly and dont drive like a lunatic.
