WOW mis-facts are nice. :/
In general or specifically on our engine? Check out the numerous GTM stage 1 SC threads, there was actually an entire thread dedicated to trying to get more power out of the SC with exhaust. Due to VVEL the intake and exhaust valve overlap is too aggresive for an FI application and causes us to loose boost through the exhaust. For example I'm running the 928 impellar AND the 9 psi pulley and I'm barely breaking 9 PSI on my Stillen kit with full exhaust
