Hi folks, does anyone know at what stage of tune that I will require an ECU upgrade?
also at what stage of tune will the factory injectors need to be upgraded?

z32 NA manual tuning
Easier to buy a turbo Z if chasing power.
Here is one companies version of the stages in modifying a NA Z (there are a couple of others too)
Basically intake/exhaust then ECU - injectors are a while away
