New Q seen where to get them, looking at a stage 2 that holds 160-220bhp or theres the stage 3 that holds 210-280bhp, do i have to be running these figers to benifit from the turbo or if i bought the stage 3 and my car was only running 180bhp will it put the bhp up even more.

I dont wanna buy the stage 2 then get my rs over 220bhp then have to buy the stage 3.

Thanks guys
