Tuning guide

Hi all, i own a s70 t5, recently carried out this work.
All disks replaced
All Calipers
Springs and shocks upgraded 30mm drop
new brake hoses
Oil and filter
Fuel filter
Plugs
K and Npanel filter
Wastegate
Boost solenoid
BSR 3 inch down pipe and 2.5 inch simons exhaust.
Stage 1 remap
So i would like to achieve 340 ish bhp and need to know what else needs to be done to achieve this. baring in mind its an auto transmission.
Any advice and pointers as to where to get parts to achieve this would be grateful.
Thanks all.

To get to that bhp you will need.

Bigger MAF (ideally 3.5")
Bigger injectors ( 550cc or VXR injectors)
And a larger turbo ( kkk24)
Then a good map for the above upgrades.

And lastly a manual conversion as the auto box will only last 5 minutes with that sort of power going through it.
