The reason it's essential to have a low psi actuator is so that you can even run a turbo at those boost levels. One of the reasons turbocharging a n/a subaru motor was considered dangerous back in the day was due to people slapping a standard wrx turbocharger on it - which had a minimum 8psi actuator. About 2-3 psi past what they could reliably run.
It's a key factor in any of our turbo kits for n/a vehicles, testing them for the boost levels they can run, and making sure we engineer the kits to run at those boost levels. That's why we have customer that have been running those kits on their cars for 5+ years, a few even 10.

I think some would be interested in the adjustable actuator (essentially an MBC) when running e85. I can already see some people grabbing the kit and getting a separate e85 tune.
