Well, if your going to ask then tell us we are wrong then why bother? Some of us have been doing this much longer than you.

Here is a basic image of proof:

550cc/min injectors flow 550cc at 43.5 PSI fuel pressure.
A Base map could have a value of "30" at a given RPM and Map pressure.

For example purposes lets say the map had a value of 30 in the bin for 3500 rpm X 10psi.

Now at that bin 30(%) of 550cc/min is 165cc/min.

Now you want to run higher boost
you only want to affect the bins that feed the higher boost pressure but since you adjusted the 1:1 regulator lets see what it does to the 3500 X 10psi bin.

the 3500rpm X 10psi bin is still at a value of "30" but now the fuel pressure is at 50psi because you upped it right.

550cc/min at 43psi is 550cc/min flow rate but.....
550cc/min at 50psi is now 590cc/min.

so 590cc/min at a 30(%) value is now flowing 177cc/min of fuel.

The rate of change is not linear so changing 7psi on fuel pressure around 43psi is not the same as changing 7psi fo pressure at 17psi.

I hope this makes sense because if it doesnt you hve a lot of thinking to do or just take our word for it. Liek I said, we have been doing this a lot longer than you.

This will be the last help i give you until you start learning to listen to what we try to teach you.
