i am thinking to mod to straight flow for my Na Altezza(6MT), is it worth to do that? any other thing can improve my power besides of modding turbo or supercharge. i dont wan mod a lot, if possible wanna keep it...
Been wondering since some Altezza is with Traction control features and some do not,
what is the effect of de-activating traction control (TRC off) on an Altezza...
