Air flow meter

[Daniel]

That sounds a bit odd as the Aussie cars are down on power compared to the
Camaro / Firebird
I know that Holden put a exhaust restriction in the non HSV cars where the
header flange is. Put the HSV exhaust on and its straight up to 250KW.
Our PCM is supposedly detuned as well as runs a lot richer at WOT than the
yank cars.
