where do i go next with my my99 uk turbo current spec is:

Knocklink
Air fuel meter

Engine Mods:
Full exhaust,decat with TSL group 'N' backbox.
ITG panel filter,
Uprated Walbro Fuel pump and pressure regulator,
TD05 turbo upgrade
TEK3 ECU mapped by Bob
Several dyno graphs but last showing 297bhp on a warm day

firstly i wanna get a short shifter and a half decent clutch when it goes but as for more power

is water injection, and a better intercooler worth seeking out, not really wanting to get a fmic. also need some info about tek3 ecu as i'm new i'm told its good but i dunno , basically just trying to learn as much as i can. be nice to hear from the uk turbo big bhp/torque boys as to what they are running etc

 

headers,up-pipe,bigger injectors.
then back to bob for a tweak ;-)

 

How about uprating the brakes and a getting the geometry done (assuming you have not done so already?
