Default Motion Lab Tuning, new 2011 STi - Big results - why a good tune is critical...

Shop: Motion Lab Tuning
Dyno Type: Dyno Dynamics
Boost: 23.5psi ----> 15psi
Fuel: 93 oct
Target AFR: NA
SAE Corrections: Default Corrections
Peak HP at RPM: 295whp @ 5500 RPMs
Peak Torque at RPM: 335wtq @ 3400 RPMs
Transmission: Stock 6-speed
Gear: 4rd
Fuel: 93oct Unleaded

Power Modifications:
- AEM CAI
- 3.0" Downpipe/midpipe (catless)

I'm very impressed with the new STi! So few mods and this power was able to be extracted. Notice we didn't use a 3-port BCS either as the factory BCS proved to be up to the task.

We performed several baselines with with the above mentioned mods on the factory tune. Obviously the non-tuned graph is a bit rough (and a little lean in spots). We mention this because we see so many auto enthusiasts throwing on mods without any real tuning performed. Following those pulls, we then got to work on getting some serious power down.

Enjoy!


FINAL "TUNED "GRAPH
[b]


BASELINE
GRAPH



TUNED VS BASELINE




BOOST: TUNED VS BASELINE

[b]



Added 4th gear pull on the street. Had the car for a little while earlier. Keep in mind, engine load is following WITH boost pressure. This car of course had the AEM intake so the MAFv and load are different from stock.







Here are some pics of the stock catback at the rear. As you can see, very small diameter piping.

wow that looks great. I def agree with a tune after any modifications are done. sure the ecu can learn but it only goes so far.

On a side note what turbo does the new sti come with?

Wow that turbo falls hard. Not sure if it's because the taper is so large but ouch. My max HP is at 5900rpm and drops 30hp to 6600rpm redline. Dropping almost 60hp from max to redline has to feel a little sad no? That lil snail needs some injectors for more boost top end

Adding injectors won't allow more boost. On Any stage2 vf car the turbo is already maxed.

LOL. I dont get the title or disclaimer, but i will be constructive. A good tune would take out 3-4 psi and up the timing. A stg2 car should only fall 8-9% from peak power to 7k on 93.

The added boost pops a punch, but the added heat kills it upstairs.

I can feel the heat off those cooking heads from here...

Aggressive tune + stock pistons = one bad knock away from a rebuild.

Power peak at 5200rpm? Timing curve and AVCS maps need serious work

So apparently you guys are upet by th disclaimer. I put that there to stop the whining. I guess it hurt some feelings.

This tune is as it was intended to be. You don't like, keep it to yourself.

Prove it then. A good tune is one that makes power/torque and is safe. Exactly what this does.

You're 100% correct. I've always thought black magic tuning was rediculous. However, we are able to keep the boost under control via other methods. No need for your sarcasm.

You're a smart man! And you're also correct, the "tuned" graph is obviously very smooth compared to the non-tuned graph. Thanks for not being part of the nasioc bandwagon haters.

I will remind you, sir, people will say what they want to say. And if somebody doesn't like what you are trying to portray, they can say whatever the ef they want. And there isn't a damn thing you can do about it. Is there? No. Can you say what you want? Damn right you can. It's a free country, a free forum where anybody can discuss anything or voice any opinions all day, every day. If you don't like what people have to say, well that's just too damn bad. You will never be able to control what people say, or what people think. So get that out of your head now. That being said, I don't like the tune or your disclaimer. Now you can defend yourself all you want. It doesn't matter to me. I said what I had to say....and it is, what it is.

Keep on trucking motion lab, still wish you had your MD though.

We do that on 2 litres overhere with (far) less boost in the mid range.
And still we're being warned that VF series are not build for going over 21psi......
So do you warn your customers as well ? That they'll kill their turbo's driving with these boost levels within 15.000 miles ?
And please adjust your attitude Motion Lab Tuning ?
It's not what you say, but how you say it !
Thank you.

I ran 23psi on my vf turbo for 3 years. Took it off with 0 shaft play. Why is the subaru community so worried about boost? We have to bring the evo guys back down to earth every now and then cause they all want to run 40psi. No we don't warn our customers, we tell them to drive the car how they want and enjoy it the tune is safe.


Thanks,
Alex Goodwin

Who cares about evo owners and how much boost they run? How is that in any way shape or form relevant to this conversation?
Their cars have iron blocks, bigger turbos, and pretty much different everything aside from the general "turbo and awd".
