I dont see much wrong with a turbo spooling full boost around 4k on a stock bottom end as its much easier on the connecting rods than one which making mounds of torque at a really low RPM (pre-3k). That is obviously more fun, but less advisable for a stock blocker for longevity.

The STS may not be able to make 600+, but its not quite as rough on your con rods with the high RPM spool either.

This is why you use timing to "ease" into it if you wish. A ST (close to the engine) will spool up by 3500rpm, you can see that in post #42, as peak tq is reached by 3500rpm. At the same time you can use timing and cam phasing to keep the torque lower/flat, to prevent rod damage. There is a lot more to tuning than just a/f.

Add to that RPM, Speed, and/or gear-based boost target tuning if you have an appropriate boost controller.

Sounds cooler when it takes a while to spool though... lol
