So i have just dropped my 2000 VX Calais LS1 to Gareth at Willall Racing in S.A for a 220/220 comp cam and valve springs. When i bought the Calais it already had 2.5" xforce system with hi flow cats and extractors, OTR with maffless tune, shift kitted and LS1 edit. It made 226rwkw on the inital power run and i have taken before vids of the idle, rev and 0-120ish. I pick her up tomorrow afternoon and i am beside myself with excitement! Watch this space.
