Hi guys,

I know this is an old thread, but I am finishing up with my Portfueler installation and I am hoping to begin tuning it late this week into this weekend.

It seems like the consensus is that a good way to start is to do a 3rd gear pull and log air/fuel data, and then use the select all feature on the Portfueler, and take off fuel accross the board. Repeat this until I get to around 11 air/fuel ratio across the board and then tune individual cells from there.

My question is, every time I use select all and take off from all cells, how much do you recommend I take off each time?

Thanks,
