do u know what a dyno is for??

HOw to increase air flow, if by changing parts ??

use Quad Throttle ? tuned intake piping ? bigger intake plenum or what ???

stuff like modding the cylinder head. making changes to the venturis.

upsizing the throttle bore don't really help airflow, that's more to increasing the amount of air coming in.

you can increase airflow with tuning maa by 3) Tweaking the valve cycle. If you make a bit of valve in/ex overlap you can increase flow :)

A/F reading depends on petrol . good petrol can run leaner with more power.:) so 12.6 is sometime too rich for power

Sweet...what does mine say? :D :D :D :D

ur right and wrong about the valve overlap. if u have more valve overlap u have higher air flow at higher rpm but lower air flow at lower rpm and vice versa as well. so if u think about averaging it out it would be about the same.

about the siemens computer, my a/f ratio is all over the place. i have 267 degree cams on both intake and exhaust, too much for my stock ecu to handle. my SAFC at idle is -20% :S
