I have been looking at your stage 2 and 3 cams for the ecotec for a year. When does each Cam start to make noticeable power over the stock power band? Are your KW figures based on any other modifications, i.e. exhaust, headers, intake etc?Are the KW figur

Each stage moves the power band up the RPM range. Can you please advise which model commodore / ecotec you will be using, so we can provide the correct figures? Our figures are based on an average across stock and modified cars, hence the power range quoted for each stage and brand.Yes the KW figures are based on a v6 ecotec with stock internals.
