When the car was brought to me it had a horrible calibration. The car would barely drive. The car wouldnt idle. I could go on and on. So I wiped that calibration and started from a startup calibration I use. I started at 5.8lbs / 6lbs because that was his wastegate spring. I maxed out the fuel table two times so I needed a bit more resolution. Like Lancerman said. Something in the fuel system was off. If I would have gone straight to 16lbs the injectors would have gone over 100% duty cycle and it would have leaned out. I wont be there all night and go up 4lbs though You're right though. I try to tune ignition tables in 2lb to 3lb increments. Even though two cars have the same motor with similar setups doesnt they're going to like the same ignition timing values
