Looked at different threads on here and got a general idea on what people have done to get more power. I have a 2004 1.7 cdti Astra H 100bhp. Im after about the same power as a 1.9 Astra 150 but im not far off being 19 so insurance is an issue lol!
What can I do to get it to this, read that boxes more than likely damage the engine so would ideally be after remap. But what else can I do to gain this extra power as I think the boxes or remaps gain about 30 bhp as average? Thanks
