Why?

Why not just insert the correct data from the start?

Jason, have a rewire?

If so, the IFR is the same all across.

Same with the offsets.

You'll want to find good data on your injectors and use that.

Also use the rated flow rate and the calc built into HPT to find out the flow of your injectors at 3.5 BAR.
