The highest number I have seen is 408 at full throttle. I would like to know your Airflow at full throttle. Please also tell me your modifications (if you use a SIP or original hose with filter box, bigger exhaust or not, better turbo etc). I have following mods: Mitsubishi TD04-19T Pro Alloy FMIC Gtec2 NGK BKUR 7ET Blueflame 2.75" from turbo and all the way to the bumper Motorsport 100 cells race cat Pro Alloy SIP with Apexi Cone filter Forge DV006 Malpassi FPR 1:1.2 Armval BCV11 set to 1.25 bar Coupé Fiat 20V Turbo Plus 1999, T19 Mitsubishi turbo https://youtu.be/O9qrLj3Ap00 Now FCP Stage3!

Ok so the max value is 408 $\:\)$ How does the ECU know how much air that goes into to the engine then if I have more than 408 m3/h?

Webbo Unregistered W	Not sure but I think it only uses the AFM reading on closed loop to get the AFR right. On medium-full throttle I think it just reverts to open loop maps which are based on the throttle position sensor, revs etc but I'm sure somebody will be along to give a slightly better explanation!
