Want to compare stock log

[The_MuffinMan25]

I am trying to compare someone else's completely stock vehicle log of driving/boosting.

About to install hpfp internals and seal kit and log again to compare.

Just wanted to see how the car is running/if anything is off.

Everything looks good as far as I see just am curious.

If the tune is the same then the only difference you may see with upgraded HPFP internals is a slightly elevated fuel rail pressure. And even that may not be a consistent difference because the pressure is regulated by the spill valve on top of the HPFP. I guess if we could log it the only consistent difference you'd see would be a higher duty cycle of the spill valve during mid to high load operation.
