How does this compare to a Stage 1 from the older STI's? Besides slight loss of low end power from the slower spooling turbo, it does make more power once on boost, and quite a bit more in the midrange. This is exactly what this car needs, just a bit more low end and mid-range grunt. I am only saying that because the results will vary and Cobb's maps may be more or less HP from here. As you can see, running more boost makes and additional 25WHP and 50ft-lbs of torque. The above graph is NOT the normal Cobb Stage 1 map, but a custom map done on our dyno to our specific car. The additional 2psi we can run at 5000-5500, really helps make peak power much higher than found on old cars. On the 2015, I am finding that we can hold peak boost much longer than before and more at redline. Older cars is that 14psi at 6500 was always about the most you could get because of the limits of the wastegate and smaller turbo. It is the same turbo part number as found on older cars (VF48), but something seemed different.Įvidence of this can be found with boost levels we can tune to.

With exhaust system and other mods like an intake, for sure there will be more HP to gain.Īfter spending about a half a tank of gas tuning, pushing and finding the limits of ignition timing, we did find a few interesting things. As we mentioned before about the laggier turbo, and the fact it was making more HP than older models, we suspected a change to the turbo it self. Keep in mind this is all done on stock STI. No matter the boost or timing, it just didn't make anymore. Only thing that was different is that we really were not able to gain any more power from about 6000 RPM on. We quickly saw more WHP than we would see on a normal Stage 1 tune from a 2008-14 STI. Since we have enough experience to know what kind of boost levels we can run on a stock STI, we stuck to those levels of about 19psi at lower RPM and tapered it off to redline.
After installing the Accessport and applying some of the basics to the map we saw pretty awesome gains starting to appear. Our car came up with about 260 Wheel HP and 265 ft-lbs of torque. This is important as it had been running around on 92 octane Oregon fuel for a couple of weeks. Staring out the day we did a bunch of baseline runs with out the Accessport installed. Its not really important for the normal customer, but essentially its all the same, except for that weird added lag and additional HP it starts with. Essentially all the same maps are available to tune on the 2015 STI, but there are a few that changed that simplify ignition timing as well as effect it in different ways.

Lance from Cobb came over to give me a few pointers about some of the minor changes in the software and also hand delivered our V3 Accessport.

Also, I felt pretty special getting serial number 2 (#1 went to Cobb) of the new part number AP3-SUB-004! So how did this tune? It also helps us with R&D on new parts we will be offering, and of course its a great way for us to help Cobb with making sure there are no bugs with the software. We were lucky to have this offered to us as it gives us something to keep the hype going with PERRIN and the 2015 STI. We were slightly concerned that Subaru may have really pushed the car with the newest ECU tune and there wouldn't be much for us to gain from an ECU tune.Ĭobb offered us an Accessport for the 2015 STI long before they were released to the public.
We showed how the 2015 STI spools slower than the 2008-2014 STI,yet still makes more power by about 20 Wheel HP. We last left you with the dyno graphs from the stock 2015 STI and WRX.
