Ian. The extra boost is from an aftermarket product I'm testing. I'm using the AP3 to monitor for knock etc and to look for a few other bugs. Not to be an A-whole, but its not my design, my product, or my investment to talk about. I'm merely an experienced "turbo guy" giving feedback. But it has shown that that stock turbo can produce another bit of boost without knock. How/if you guys can make it do that with the cobb software is another matter. I haven't got to use/experiment with the race tuner software. All I can do is say if the "OTS" tunes work with this product or not. And so far. It works AWESOME. This thing is an animal in 6th on the interstate.
If someone were to not have the AP3, and they wanted more power at a much lower cost, is product will be the way to go. Its really a totally different product versus the AP3. The AP has infinite EVERYTHING really, and gauges, and CEL reset, and datalogging. But this product will be about to match or beat the power numbers the AP3 puts on the dyno, although it will come up short in all those other areas. Cost to benefit ratio will be in its favor.
If cobb/anyone figures out or forces the stock ecu to increase boost pressures, then the people that already have AP3's need not worry. But if no one figures out how to increase the boost per rpm then this product will be value to people without the AP as well as with the AP ( like me currently ).
I can say this... Its not been on a dyno. But when I took my GF out in the car with it installed she looked at me and said, "ok, what did you do to it? "Feisty" feels a whole lot "Feisty-er" tonight.
