Turbo Replacement: Which Turbo to Choose?

Hello everyone,

I was wondering which larger loader I could use to better utilize the potential of the 0.216 nozzles.
I have an ASV (presumably referring to a specific type of vehicle or engine) with the original turbocharger, 0.216-size injectors, and customized software. If I remember correctly, I'm running a maximum boost pressure of 1.3 bar, which means I'm close to the limit of my turbocharger.
Therefore, the question now arises of needing a larger loader. Unfortunately, I'm not really familiar with the corresponding terminology or differences.
I would be grateful for any information or advice you can provide.
