i know there's afew mappers/tuners here so maybe someone could answer this...

right.. my afr with the standard airbox is 13.2 at wot

but with a piperx venom filter its 12.2 at wot

so..by this, does it mean my airbox flows better than the venom?

car inquestion is a mk6 escort with a 2.3 engine running rs2k ecu (no chip)

(have megasquirt to fit in the future)

thanks.
