DSM 450cc's?

Ive heard both ends of the story weather a tune with 450s is completly necessary or not
so is it possible to run stock tune with DSM 450cc injectors and intake/exhaust?

Short answer no. You will run pig rich and make your car slower. You could end up spinning a bearing due to too much fuel getting into your oil.

Get at least a SAFC2

alrighty, thanks.
Im not actually running them right now, i just have them and checking out what the whole peramiters would be
