Cobb Tuning is Fountain Valley does pro tunes on a dyno I believe. They're OTS maps are pretty conservative because they need to consider different climates, elevations, etc. You being at sea level in a mild climate, you should be able to make some decent gains with a protune.

You can also make a custom map for higher octanes. A good way to do that would be to go there with maybe 1/4 tank of 91 swill and do that tune. Then next there's a 76 station not to far down the road that has pump VP100. Filler up with hundo and you'll have a tank of high 90's gas. In my Subaru, the difference between 91 and 100 tunes in my Subaru was 62 lbs wtq 40 whp. It was a weekend warrior so I always ran 100 on the streets. At that time I was paying $7.99/gal and getting a little over 14 mpg. Sure was fun though.

I'm new to this, and BMWs as well. But it seems to me that GAIC is pretty much the same process as COBB, but with less flexability and end user adjustability. Seems like GAIC just didn't go the extra step and produce a packaged product. COBB is a slick looking little gadget, and you can turn it on or off, make changes, etc . So why should the dealer have the exclusive rights to the input/output of the ECU? I want that access. In the Honda world, Hondata had the strangle hold on ECU reflashing but you had to send them your ECU and it was only for a specific set-up, with no adjustability. I would not even think about a piggy back type tune. DO it right, program the ECU right?

My '08 is stock, and I just want a little more pull with complete reliability.

Does anyone know what the COBB does to fuel economy under normal driving conditions? And what about stop and go - does it keep the timing advanced when you're just putting around?

BTW, I cot the COBB AP, and it's kick ass. No dyno or none of that, but it's pretty scary. Much more grunt, mid range, and the rev limiter is higher so the needle swings way up there pushing the speedo way up into the felony zone. I'm trying to stay out of jail. I can here the turbos spinning up too.

The AP is really cool, and I would get one just for the ease of use and the reputation (Cobb has been working in the Subie market for a very long time), if I didn't run meth and love my gauge hijacking. So I really don't doubt Cobb's research, and im 99% sure (because I doubt even Cobb can be 100% sure) that the boost numbers are fine and safe.. it's just strange that there is that discrepancy and some worry-worts may not like that.

Either way, a pissing match between tunes that put nearly identical power, both cost below 1 grand, both have great features, reputable companies behind them, and are simply both awesome is dumb. We all have the same car and different things work for different people. Everything from supporting mods to your mileage and how much carbon is gunking your engine can affect the power output and race results, but both mods have loyal fan bases and are awesome, and this really tells you that there's no going wrong with either one.

And here is the above mentioned magic chart, which was recently updated (and which I love to link, because it really tells you all you need to know and EVERYTHING else is subjective):

Thank you so much for this!
