its really hard to explain what it does but...

i have the interceptor gauge and it tells me the throttle position and whenever i give around 50-100% throttle the rpms goes up n down up and down and gives no power to the wheels but u can hear the turbo working and pushing air in the motor

and just to add a lil more knowledge i used to have the innovative 50mm turbo from z7 kit but that one blew soo i now have a turbonetics 60mm with a bigger a/r (.82)

maybe my new turbo pushes more air? and its my maf sensor?
