As a newbie to your forum let me introduce myself first so you all know where I am coming from. I own a '97 Mitsubishi Eclipse GSX that has been heavily modified and is currently for sale since my interest in an RX-8.

My question is: Since most of the dynos that have been reported to lose Hp after 6250 rpms would an aftermarket piggyback system (ie. S-AFC) work on improving the dyno plots? I only say this because it seems that this would potentially work in the cars that supposedly begin to run extremely rich after 6K rpms.

Any and all insights would be greatly appreciated.

Thank you.
