are you pulling the car forward or winding it forward.
the choke of a dp intake will pull you to the internal "wing" velocity. idle to 3000 will happen quickly in a performer.
a single has no hi end choke off other than internal volumn. so if you are winding past the 3000 with a stall you can enjoy the top end benefit. it wont make your performer cammed engine pull to 6500rpm.
