Anybody been playing around with the throttle stop setting on your throttle body?
They're set at factory and shouldn't be touched.

welcome to the club, mine burning a tank in 220km..and not heavy on the gas.. done the same as you and still no joy. Starting to think maybe a re-tuned memcal could be an answer. Have you had any mods done? and did you replace the breather hose from top of the tank with the originals from holden(1 goes to the filler neck, the other goes to the fuel lines) the smaller hose is genuine only. its like 5.74mm or something ridiculous like that..holden had to order it in and i put them on today, so will see if it makes any difference..

have you checked your vacuum lines both going to the tank and elsewhere around the engine bay?
