Hello I have Leon cupra auq 1.8t

I have 70mm dp
63.5 exhaust cubra
200 cells free cat
Kn air filter
Tip silicone forge 70mm
4fpr
Fmic 51mm pipes 550*18*6.5
Dv from S3
And I am thinking to crank the original Westgate and use electronic boost controller to better boost at redline and steady boost or is better to use WG adjustable?
I want 1.1 1.2 at redline and about 240 250 HP at crank is possible without wastegate forge only with boost controller and crank wastegate?
