so i saved you from other peoples remarks.

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..

Where is the chase and how do you cut to it?

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.

Is there a reason why Colorado does not offer higher octane ?

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.
