Vacuum Reference on TPI Regulator
Just wondering what everyone's thoughts were on whether or not to run a vacuum line to my holley AFPR on my TPI intake.
I was reviewing some logs and noticing some small (5-ish) flucutations in fuel pressure even at WOT. I have a 100psi fuel pressure transducer hooked to the rail to monitor the pressure.
I also noted some small differences in the WOT AFR that seem directly related to the fluctuations in fuel pressure.
I'm looking for the most consistent AFR possible. I know that disconnecting the vac line from the regulator would require modifying the VE tables but I was just wondering whether or not it would produce any real differences in the end, especially taking cam specs into consideration which directly affect vacuum.
