Message	When you've got the throttle open and the turbos are compressing the air, the MAS is reading all the air coming through it... And thus adding fuel for it... When you vent through the BOV due to a close or decrease of throttle, some of that air goes missing... but the fuel has already been calculated and added... So, how can you say it won't run rich because of BOVs? If its recirculated, then yes, it won't run rich, but 99% of BOVs on Zs are vented to the atmosphere... If you have an HKS AFR it has a component that calculates for lost air due to BOVs. Check HKS's website. I'm not sure about the AFC though. I've seen vendors site the BOV/MAS problem as fixible with the AFR and not the AFC. Peace, KaZ Dyno'd - 334.5 RWHP / 359.1 RWTQ @ 17 TDC ICQ - 22589000 / IM - KaZsMiR / E-mail - casimijg@hotmail.com
