I got my camshafts from K-tec but have stg 2 hillpower chip instead.
Theyre just piper cams if i remember correctly so you could get those anywhere and the chip is mapped for them so no worries there. One thing i will say is beware of hidden costs! If youre getting cams fitted, you will need vernier pullies to time the correctly as well (extra 170quid) and depending on the state of youre engine it may be advisable to have new followers installed (an extra 250quid). A PBV may come in handy as well.....
Can you give some info on your car? eg mileage, other mods etc...??
