Ideas for tuning my golf gti

[Kelvmelv]

Hello there 
I'm new to forums so be gentl 
I've just bought a mk4 gti 20v
I bought with a remap already done and a k&n panel filter which is producing just under 200bhp, I've read a few posts about tuning them and the agu engine seems robe more tunable? Not sure wat mine is? It's a w reg.
In the next couple weeks I'm going to buy a fmic of eBay 200 quid, and a sportex back box and race tube along with a decat :-/ ? A walbro fuel pump, was wondering if and wat injectors to get and would I need to upgrade turbo? Been looking at k04-001? What sort of bop wud this get me?
If I was to do any of this would I need to remap ecu again?
Cheers

all depends on your budget. If you don't want to upgrade the engine internals then get the k04 and 440cc injectors with supporting mods you should get to 300bhp give or take. If you go much higher than 300bhp then the rods will break.

Ok cheers will take a look at it, what supporting mod would you suggest?

full turbo back exhaust
frontmount intercooler

Make sure the engines running properly with a Cam belt check and water pump, thermostat temp sender, flywheel, intake, TIP, charge pipe...you get the idea
