General Question about baro correction w/ ITB Mode

[SteinOnkel]

Hello all,

last year I took my sea-level tuned ITB mode car w/o a barometric sensor up to about 8000'. It didn't like this and started running lean >4000'.

Since this is an annual trip, I decided to add a barometric sensor.

My question is this: do I actually need a curve? It was leaning out since it was in the wrong bins on the VE table, because the load calculations were off. In theory, can I just add a barometric sensor, tell the ms about it and leave the correction curve at 100% across the board?

Thanks
Steiny
