BOV Question

Is this true?

Putting atmospheric BOVs on wrx's and sti's make them run rich in between shifts because the MAF has already metered the air coming into the engine and has a set amount of fuel it is going to use. an atmospheric BOV vents the air that has already been metered by the MAF and the fuel is then injected into the engine with not enough air thus making the car run rich. atmospheric BOVs arent very good for wrx's and sti's

i have baileys one on my car - just wondering out of interest, i guess you would get around that if you remap... but would noticed the difference in petrol usage?
