As the title says really. I'm planning on fitting my forge fmic today and i just contacted my insurance company to inform them (i'm a good boy) , and they asked me if it increases the bhp and by how much from standard. Now i told them i haven't got a clue and they said they cant make an adjustment if i cant provide a rough bhp increase. The car is a completely standard mk3 ibiza cupra, no remap, no exhaust (yes there is some of us still out there). Can anyone help?
