Neither, a piggyback ideally, or a re-mapped oem.
You will gain nothing from using GA16 injectors, and the CG13 throttle body is good enough for 150bhp ish, before it becomes a restriction.

mine passed the emisson test ok last year (.003 CO) with a 1.6 t/b and injectors, but i think the a/f/r,s were way out at certain throttle openings (maybe a sard fuel reg would help ?)
and i think you would need cams etc to make full use of them

Do you have a wideband lambda sensor?
Your fuel pressure is also designed to drop on idle for economy and emission purposes.

The standard sensor is what is called a Narrowband sensor, which will NOT give you an accurate AF/R, you need to install a wideband one that can give an accurate reading.
An E-Manage would be adequate for a decent turbo conversion, for massive power, stand alone or a remapped OEM is the better option.
Do a search for a TechEdge 2J1, and also do some research about, open loop, closed loop, lamda sensors, MAF adn MAP sensors.

i though ed said that the map only extends to about 5k, then interpolates or just uses the previous values or something ?

k11 ecu runs both open and closed
so im not getting an accurate reading because its a narrowbwnd lambda but it seems to do the job from starting the engine from cold and lightly pressing the throttle.
from starting it, it revs at about 1400rpm with a stoichiometric ratio and as the choke wears off and the revs drop to idle crawls into lean but as soon as i boot it, it flicks straight over to rich.
so does that mean it is closed loop on idle and light throttle and open when i boot it?

A narrowband sensor reads around 14.7:1 the ecu looks for the signal to alternate between rich and lean around once per second I believe to indicate Stoich.
My car idles at 14.7 +-0.1 but that's without the narrowband signal connected, so it may be normal for the car to idle at a leaner mixture for both emissions and economy.
N/A cars produce maximum power around 13:1 usually, so this is why your car will go rich when you boot it.
The only thing you can really read with a narrowband is: Ok, Rich, Lean. It won't give you an accurate reading of what the mixture is.
