I wouldn't go as far to say that there is any "power tweaking" due to the adrenaline....only because there is only so much oil pressure commanded in the programming and going any higher can result in undesirable operation.

The main issue with higher displacement HPO pumps is the base injection pressure regulator map at idle or just off idle conditions. You can end up with a "rolling" idle or choppy idle with a HPOP upgrade and no tuning fixes for IPR duty cycle.
