I am running a 90 scirocco on throttle bodies from an r6 yamaha. Where do i take my map reading from? There is no manifold as such. Each throttle body is attached directly to each intake port. Would i connect each throttle body vacuum line together then connect it to the map sensor.

Thanks

Gentlemen, thank you.

Just one more piece of advice please. Should I drill a small hole in each throttle body and feed the vacuum line in there?
