I've had excellent results using Speed Density (MAP) tuning, but, as has been mentioned, you can try alternative methods of tuning. I've also had excellent results with Alpha-N (TPS) tuning. There is also the ITB method that is a blend of MAP & TPS. (MAP has better resolution at low RPMs and TPS better at higher RPMs)

I hope to stay with MAP for now. The engine responds very well at WOT. I'm still using Tony's Bitz kit with MS1, but I have a MS2 on the shelf and may change this winter and ad ignition as well.

No data logging yet, this was just a quick spin of a few miles to see how it felt. I'll make sure to log next time.
