Notable cars seen on the road today during my travels - 2 FR-S, 1 BR-Z (first one I've seen), 1 9G Accord Sport, and 3 Panameras.

I think I'm set on the ST...
Damn impressive gains with just a tune. Look at the torque!
253/324 to the wheels! Peak torque at 2346RPM...

SCT vs Stock Calibration Notes:
Same SCT calibration was tested on both 87 and 93....power is down about 15fwhp on 87 vs 93.
NOTE: SCT recommends 93 or 91 octane.
The big deal is the power gain when the car is "hot" and at normal drive temp (99% of your time)
Stock Boost Levels- Stock the ST will make spikes of boost around
21.5 psi and then holds between 20psi - 17psi, depending on the commanded torque.
SCT Calibration Boost Levels - SCT 93 Octane Calibration the ST will make spikes of boost around 23.5 psi and then holds between 22.5psi
- 17psi, depending on the commanded torque.
Air Inlet Temps are very good.....after 10 minutes of idle time and
7 runs in a row they climbed from 80F (run 1) to 110F (run 7).
Stock Speed Limit is 186mph
Stock Rev Limit is 6700rpm
SCT Calibration Rev Limit is 7300rpm
Torque Truncation has been eliminated
Now, the car remains an ANIMAL on the street after it has some heat in it.
I am also putting together a group buy for the SCT X3 programmer $ 399 through October.

Really? I love winding it up, especially when a light turns green on a high speed-limit road or highway on-ramp.

GTI's fall off too, i think turbos just do that in general?? They run out of air up top.
anywhoo, you think that tune will yank at your steering wheel?? It is still a fwd car.

That's why variable-vanes are popular, no?It's part necessity
I do enjoy doing it in any car though.

^well i dont know too much about turbos, but i'm sure that size matters too. Just saying its a common trait of a turbo? And brb while i google variable vane turbos haah

My MS6 in stock tune falls flat on it's face after 5500 RPM too, but Cobb has eliminated that problem to my redline loving delight.

On the topic of tunes, what are the downsides? All we hear are improved power, improved fuel economy, improved everything.
Is it just a little less reliable?

But most of the time I wouldn't imagine much risk other than perhaps some premature wear from being under more pressure more often.
My guess.

There are ways to mix and match the halves as well, so you can tailor the snail to the motor.
For example: Subaru recommends at least 91 octane in my car since thats what the tune is setup for. The tune I have now is spec'd specifically for 93 octane, so timing is a bit more aggressive and the fuel trims are cleaned up a bit. I can run 87 octane in an emergency, but I have to drive real easy on the car.
Im sure that the ST can make another 20-40whp/tq on corn juice too.

Most manufacturers very conservatively tune their F/I vehicles in order to maximize reliability *glares at Volkswagen*
Other times, it's baffling. I believe on early Mazda DISI motors (2.3 turbo, MS3/6), the stock tune is actually more prone than it should be to deonation, though I may be missing some details. It's prevalent enough to the point where MS owners even coined the term ZZB (Zoom Zoom Boom)
Nothing API or an Accessport can't fix!

UA6's SRT-8 thread reminded me... whatever the hell happened to these? I'd imagine these are a lower-cost alternative to ventilated seats.
The crotch vent is just as important as well the other vents. Swamp crotch is more uncomfortable than anything else. Also found another name for these vents: ball blowers... heh

Drove our '07 Carrera S today & felt right at home surprisingly with it being a stick. Stiff clutch, yet still gives you enough feedback to know when its biting. Kind of surprised me because with the PDK transmission, you have to ease into the gas pedal to find the "bite" point I guess & it's tricky because the car will sometimes shudder a bit (as if stalling) & then just launch when you try to give it a little more throttle. The ones I've driven so far (par Boxster), I've yet to get the car to gently ease into motion; they always want to take off. So, it actually felt easier with the manual. 
Afterwards, had a chance to drive '13 Boxster. It had the PDK tranny as well, but the throttle response was much easier without the car wanting to take off. I've never driven a previous Boxster before though, but I can't imagine just what kind of improvements were done because it's an amazing, little car.
Definitely made me want the Carrera S until I realized I can't afford a $57,000 car.

The real reason for ZZB though is the car being a relative performance bargain being put into the hands of kids just getting their license and thinking it's a race car. More often than not it's because of simple abuse, dropping the hammer on it constantly or boosting at too low RPMs causing all that excessive boost in the cylinders. There has been it happening (supposedly) to someone while just crusing at a steady speed out of boost, but I'm suspicious about that. But I personally run an off the shelf COBB tune simply because it's much better than the stock tune but still safe enough that I'm not pushing the limit since this is my daily driver. Some MS6/MS3 guys are tuning on E85 and making HUGE power. It's not uncommon to see 500+ hp out of the DISIs now, of course with big turbos, not stock units, but still that's insane for a sub-$30,000 car IMO.

My order will be the first ST3 that arrives at my dealer - needless to say my rep said they were anxious to see one!
On another note, I already ordered the SCT Custom Programmer and tune since it's on sale for the month of October. I'll also order the JBR rear motor mount to reduce wheel hop, the Steeda CAI when it is released, Steeda rear swaybar, and eventually a nice cat back exhaust. So it begins.
