Why stop at 300bhp? If you're going to go for it I'd go high 300's (sure some Leons on here run 360ish). There again being rational there is the issue of standard internals (doh!).I have 300 odd and it barely feels any different to 270 in my stage 2 Leon. I'd suggest you aim higher if you really want to feel the difference. It wouldn't cost that much more.
