hi andrew,
u dont need a power fc unless ur upgrading injectors/turbos.
the standard unmapped ecu is good for 270kw +.
weve done a few lately with this sort of power on standard ecu.
u may need a fuel pump though,above 250kw is a little risky on standard pump,nothin worse than a top end lean out.
u may need an adjustable reg above 250kw.
250kw-mid 12s ,come on meggala.only if ur grannys driving.
250kw is good for mid to high 11s if u know what ur doin.
both costas and shauns r32 went mid to high 11s with this sort of power. .costas standard ecu and i think shauns to.
dont worry andrew when u pick it up from me after ive had it tuned for you ,it will rip anything up your way in the sticks.
