I recently changed maps and have a feeling my old map was running a solid 20psi (as in maxing out the main boost gauge, without ever going over).

The revised map looks to be running 17.5psi, although I can see it peaks at circa 18/19psi for a split second before it settles.

It still feels very fast in the lower gears, and whilst it could be my imagination, I am wondering if there is less urgency in the longer gears.

What boost are others running on stock tubs and internals? My car is stage 4.25 by the way.
