link g4 to tune 6 throttle bodies

hi, i am using the link to tune a s54 m3 e46 engine swapped into an e30 bmw.so my question: Is it better to tune a 6 throttle bodies s54 N.A engine fuel table using the tps as the load axis, or can i simply tune it with the map being the load axis. what are the disadvantages when tuning it as the map being the load axis?

Here's a webinar that Andre done a while ago covering a boosted ITB engine (RB26DETT), he explains really well the major differences in why you need to tune via Alpha-N rather than MAP
