Mark, thanks for that, much appreciated, looks like i was thinking along the right lines.

re: amm
I dont like airflow meters (or air mass), would prefer not to use one if i dont have to.

re: hassle
Its not any hassle ive got them sat here complete with a manifold and plenum all made up ready to bolt on, so providing i can get a half decent map sorted its not an issue.


cheers everyone for your input
