I initially set my fuel pressure on my fuel lab regulator to 38 psi many months ago. Well yesterday I was trying to do some open loop tuning and glanced at my liquid filled gauge and realized my pressure was low ( 30psi with vacuum line capped) at idle. So I adjusted it and re tuned (lowered Maf sliders) and today I start the car up and see my pressure has increased at operating temp to 50psi with line capped at idle. So I re adjusted the line to 38psi capped and going to check it another day to see where it's at.
Question is I have never noticed it drop before like that after doing pulls but is it possible that the afpr can drop pressure and regain itself and I happen to catch it while it was at low pressure?
Re wired 190lph, fuel lab afpr, and 1150c fic. I want to get a better understanding of what's going on so I can resume my tuning and not worry about my fuel pressure changing .
