Apparently the gen2,s narrowband pulls the airfuel back to 14.7 in the busgo range anyway.90-130k,s up to 30% throttle with non stock cans fitted,everywhere else it has no influence.An inquisitive mind with a dyno discovered this.AN inquisitive mind would also look at what happens to the secondary butterflies throughout the rpm range in different gears,and then fit a tre and see the difference.I still believe the factory has restricted the gen2,s quite a bit in the lower gears in a few different ways,ecu flashing later in the year will see by how much.theres more than one way to skin a cat.It seem no one with a gen2 has a knife or a cat.
