I have a VX Berlina V6. I have a Mace CAI on already but this time my budget is higher at about $1,000. I was looking at a comp stage 2 cam at $480. The PCM was also tempting for the improved shift points. The main thing I am looking for is low down power

Given your budget of around 1k and desired improvements in low down power and acceleration, we'd recommend the following packages instead of a cam upgrade as shown below. Package 1 COLD AIR INTAKE MANIFOLD INSULATOR 25MM FOR HOLDEN VX - VY ECOTEC http://www.maceengineering.com.au/epages/shop.sf/en_AU/?ObjectID=1469397 $220 PERFORMANCE 12mm PLENUM/MANIFOLD SPACER! Holden V6 VS-VY http://www.maceengineering.com.au/epages/shop.sf/en_AU/?ObjectID=1469462 $150 BORED OUT 69MM THROTTLE BODY! For Holden VS-VY http://www.maceengineering.com.au/epages/shop.sf/en_AU/?ObjectID=1470093 $220 HOLDEN RECALIBRATED COMPUTER/PCM TO SUIT VU-VX V6 http://www.maceengineering.com.au/epages/shop.sf/en_AU/?ObjectPath=/Shops/mace/Products/COMP611/SubProducts/COMP617 $280 HIGH RATIO ROLLER ROCKERS FOR HOLDEN ECOTEC AND L67 V6 http://www.maceengineering.com.au/epages/shop.sf/en_AU/?ObjectID=1469592 $495 Package 2 COLD AIR INTAKE MANIFOLD INSULATOR 25MM FOR HOLDEN VX - VY ECOTEC http://www.maceengineering.com.au/epages/shop.sf/en_AU/?ObjectID=1469397 $220 PERFORMANCE 12mm PLENUM/MANIFOLD SPACER! Holden V6 VS-VY http://www.maceengineering.com.au/epages/shop.sf/en_AU/?ObjectID=1469462 $150 HIGH RATIO ROLLER ROCKERS FOR HOLDEN ECOTEC AND L67 V6 http://www.maceengineering.com.au/epages/shop.sf/en_AU/?ObjectID=1469592 $495 In summary Package 1 offers the greatest power gains possible in the low to mid range. Package 2 does compromises some of the power gains down low of Package 1, however it more then makes up for it in the top end which would arguably result in a faster car if the engine is pushed to the rev limit.
