Secondary Butterflies?
#1
Has anyone here ever done the Throttle body mods that consists of:
removing the Two Small (Upper) Throttle body butterfly valves?
Is there any increase in.... Tourqe - or - high Rpm Power?
Is there an increase in anything?
Thanks markus
If so, what else has to be done... other than just un bolting the butterfly valves?
