At what point do I need a management/ a tuner / tune.
I have a Rb25det with a gearbox. I was thinking about replacing the turbo with something a bit bigger. Complete with a external wastegate setup. Injectors and maybe a 300zx maf.
I saw some aftermarket brains selling that have a tune with bigger injectors and the maf. Makes sense?
Would I need a management and a tune for those mods?
