You didn’t pay for numbers.
Money doesn’t equal power.
The package you have now would be more efficient, better in the mid range, more reliable and have a heap less strain on your engine to make that power.
that's about what a Bf makes on 98 fuel at 14 pound when working efficiently. Sounds about right to me.
The fact of the matter is you can give someone two cars with two different tunes and the better tune will feel faster, doesn’t mean it’s reflected on Rwkw necessarily on your dyno sheet.
Worry about how it feels not the numbers, unless you’re building a dyno queen car, in which case I suggest you change your entire approach mods wise.
To make more power on those mods on that turbo it needs more boost... which your tuner may have chosen not to do due to a bunch of factors, condition etc.
