Finally, you can always swap to a different sized turbo or vary exhaust and compressor sizes if you are not happy with your turbo profile. You can swap superchargers too, but it isn't always as easy or an option. The JRSC has the C30 and C38, but the Edelbrock kit doesn't offer a different sized blower. It is typically much easier to option a turbocharger of your desire during an initial purchase, and it is easier to make a swap later--typically.

You could somewhat replicate a turbo's boost-by-X tuning by running a wastegate on the intake tube with an electronic control or an electronic control on the internal bypass (if the blower is equipped) and smallest pulley for the upper limit of desired boost.
I haven't seen this in some years and I don't have the impression it was widely used, but back in the early/mid-oughtes when turbos were really starting to take over from superchargers in the 5.0 Mustang community, some SC users realized they could mimic the broad, linear powerband of a turbo by installing a small wastegate on the intake tube to dump excess psi. By targeting, say, 10 psi and running a 20 psi pulley, they could make 10 psi a couple thousand rpm lower in the torque curve and hold it through redline instead of making 10 psi near redline with a 10 psi pulley.
