I didn't look at the plugs. I just checked the basics, then it started raining last night. Called the dealer this morning.

Just heard back. They are replacing the HPFP under warranty. Picking up the rental here in about an hour. Should have Red back by the weekend (I hope).

Again, its about killing the learn down.

GMTU should get you 21psi

everything else stacks on that. with cat-less, IC, Piping, and intake. 24+ is sort of normal.

You should see less boost with those mods not more. But I don't know how the gms1 tune is set up so I may be wrong. If the tune stays constant and doesn't adapt to the mods then you end up with less restricting and seeing that psi is a measurement of restriction you should see less of it all the while maintaining the same amount of airflow. That's assuming the tune is looking for a specific amount of air flow though.
