Not Ranked
sounds like airflow. Also just check (a long shot I know) that when the bonnet is closed it is not pressing on any hoses. Saw this happen to a car on a dyno, it was good as gold on the dyno with the bonnet up, bonnet closed and it went all weird - turned out the bonnet was "just" touching an aftermarket fuel pressure reg.
