That depends on your budget and what you want to achieve, mate. Before embarking on more power, monitor the engine condition with boost gauge and knocklink at least.
As for power upgrade, you have loads of options including ECU upgrade (Apexi Power FC, Link, GEMS, Motec, etc), turbo upgrade or boost control (Dawes, Apexi AVC-R, Blitz Dual SBC, HKS EVC4, etc). If you have big power in mind, then make sure your fueling is up to it. Large injectors, fuel pump and adjustable fuel pressure regulator, etc.

Brakes could do with upgrade. Then move onto handling department - suspension, anti roll bar, solid drop links, anti lift kit, bump steer mod, good tyres, etc.

One word of advise, HKS mushrooms don't like MAF very much. I'd keep an eye on it regularly, or have it replaced with a dry type induction or put the standard air box back on, with an uprated panel filter.

Hope that helps

Cheers, MAF Seems fine at the moment, it doesnt hunt on idle etc, ive seen the apexi boost and AFR controllers for sale on ebay numerous times, are they any good and how would i set it up? You also mention the larger injectors and fuel pump etc, is this something i need now? and the knock link, i have never really understood this, it tells you its knocking, could you use this as an indication when setting up the apexi goodies?
