I am running a td04 at 0.92 bar and its currently running 218bhp. Now i would like a little bit more power but i dont want to put too much strain on the turbo, i have heard a few people talk about meth kits for the glanza. Now i have no idea on what this does and how it works. Also is it very dangerous and is there many things that can go wrong? I want to hit the 250bhp mark without going for a forged engine basically. Any ideas? Thanks in advance.
