SCU’s stats have been rising steadily in recently years. For Fall 2017, the SCU engineering school had a 25%-75% SAT range of 1340 - 1490. The OP’s reported SAT of 1540 is obviously above the SCU 75th percentile of 1490, but probably not a “couple of deviations” above. http://profiles.asee.org/profiles/7791/screen/19
The numbers for the SJSU engineering school are probably significantly lower, but they are not available in the asee.org profiles.
