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.
1. calcium battery (Maintenance free) is good for turbo car...
because there is no worries for maintenances. We don have to keep pouring
water into it.... it's too...
