Audi system is closed loop, BOV just messes it up, you'll be running way rich and losing power.

 

but if your running more boost dont you want more fuel? so you might be running to rich at stock boost levels, but will it even out with added boost?

 

You're reaching there OUT_T_1.8...

The ECU adjusts the fuel levels accordingly. If you are running more boost, the computer knows to add the correct amount of fuel based apon the fuel maps. No Audi should be running rich at stock boost levels, unless you have some sort of problem (aka MAF, O2 sensors).

 

yea im reachin :streeeeeeeeetch: the MR2 also recirculates the pressure. and its is taboo to vent the valve in MR2 world, but people still do it (including me) only ill effects i see is decreased gas milage and doesnt shift as smooth. i dont think its as bad as people make it out to be. but dont go thinking ur adding hp or improvong your motor, your really just paying all that money to hear "psssssssssht'

 

wrecks the cat after a while, and if something else goes wrong to ie o2 the combined over fuelling could lead to bore wash.

 

Thanks alot for the help guys I prolly would of messed it all up so i jus thought i would ask so thanks alot for all ur input!
