i saw a few drift participant and us tuner mostly prefer 20v bottom end and mate it with 16v big port head from ae92.mate it with individual throttle body wah its one of the best thing in the world since coca cola.
Hi guys, been searching for the answer on this question of mine, but I can't exactly get the answer i need. Do I need to tune vr4rs if using evo 609 MAF since vr4rs is also using 510's injectors.
