there's nothing wrong with using SURBO, whether is stage 1, stage 2, stage whatever stage that is, it's ur own money.. u wanna try trylo.. u wanna buy buy lo... there r good n bad...
for me.. it's too expensive n not worthy for a gadget that do small thing for ur car..
they claimed (from they website) when u install this to ur car, wit just half a throtle ur RPM can reached redlined..
OK.. be logical.. when we rev n reaching up to redlined... meaning to say our car is reaching the speed n speeding..
but wit this product.. only the meter indicating to REDLINED.. but not the car..
isn't that stupid!!!!!!!
