I am not wrong. You suggested that FP under 7 psi boost is 43 psi which is wrong.
Sorry, but good try.

Read my first post about this. I said when you hit full boost at 7 psi not under 7psi boost. Not sure where you got that from....
With vacuum ATTACHED (I am not talking about setting fuel pressure since it should already be set) at idle if you are running stock fuel pressure you should be at 36 psi. Since our regulators are 1:1 ratio, for every lb of boost you should see an increase of 1 psi of fp. So 36 + 7 = 43 psi.
And I guess you are not understanding my logic.....you should keep an eye on the fp gauge to make sure it keeping steady fp throughout the rpm. When you are running on the dyno, the vacuum will be attached which means your numbers don't apply. So WHEN RUNNING THE CAR at stock fp, the gauge should read 36 psi and at full boost of 7psi it should be holding 43 psi to redline.
And I never mentioned anything about you disagreeing on the topic of upgrading fpr in my second post.
