Hi all,

Im looking at getting my car mapped soon but not 100% sure about what fuel setup i should have

Should i have a parallel fuel rail set up?

also do i need a Fuel Pressure reg?

Should i change to 550s?

Im not looking for mega power, prob 330bhp

Dont need parallel set up anyway.

440cc will be fine without a fuel regulator but for piece of mind no harm installing.

recommend sx or fuelab ones. Although sytec on a budget will do the job also

440cc injectors will generally max out shortly past 320 bhp.
You do not need an FPR unless you want to extend the range of your injectors and you might get to 340 bhp. Some people claim 350 bhp so I have no idea as to fuel pressure but different rolling roads give different figures.
550cc injectors are good to around 380 plus bhp without an FPR and just over 400 with so they would give you headroom.
You most certainly do not need parallel fuel rails.
FYI, with all supporting mods your TD05 16G is capable of 340 to 350 bhp but this is with all supporting mods and an efficient front mount.
