What I did to mine:

Dreamscience Induction Kit
Dreamscience Mod C Remap
Full 3" mongoose with downpipe and sports cat
Airtec Intercooler
300bhp or there abouts. Did 290bhp before the stage 3 map

If I did it all again I'd probably get the Mountune kit and enjoy. They say it's 260bhp but guys on the rolling road were getting 280
