COBB TUNING Calibration Notes for 2004-2006 Subaru STi
AccessPORT Calibration Stage1 93 v111
Power Output: 325 HP / 340 ft-lbs which is a 40 ft-lb & 25 HP increase over stock. Peak torque is achieved by ~3800RPM compared to ~4000RPM for the stock vehicle.
We had some freak snow yesterday and today, but I finally was able to go on a short (25 min) test drive this afternoon when the sun came out and dried everything up.
I'm running the standard 93-octane base map and using 94 octane fuel. Like a lot of people have said, there's definitely smoother power delivery with the AP and less turbo lag because the power comes earlier in the RPM. It's a noticeable difference and it should have come like that from the factory....
I didn't bother to reset the ECU after flashed Stage 1. According to the live data readings on the AP (I don't have a boost gauge), I was hitting 17+ peak boost in full throttle pulls in 3rd and 4th gear. From what I've read this is normal while the ECU is still learning. Afterwards, according to the map notes, target boost should be around 16.5 psi. I can't wait to get out on the road again:0)
It should be even more fun when Cobb releases the 0-60, 1/4 updates--then I can do performance comparisons between the stock and Stage 1 maps ;0)... although, I'm already dreaming of Stage 2 :devil:.
