For example, when shifting from second to third your rpm may only drop to 4500-5000 rpm, so you may not see full boost in third on level ground (or in warm weather).
When going uphill, you can probably hit full boost in 2-5.

Funny you said that about going up hill, my 1988 toyota supra would only make 8 or so psi in second gear on a flat surface but it could make 10-11 psi going uphill that always puzzled me
