I got a pulley as part of a package of items that were removed from an SVR before sale. Is there any advantage to doing this without upgrading the software at the same time? I’ve done ECU flashes on a lot of my cars, but usually wait for the warranty to expire. Since I’ve got some time, I likely won’t do a flash soon. Anyway, the same way boost can be increased by an ECU, it can be decreased as well if the blower is putting out “too much” air mechanically. (Just open a wastegate.) Am I right in assuming that just swapping the pulley is unlikely to lead to much of a gain? Thanks for any input.
