Good afternoon anyone have any product review of BBK Power-Plus Series Throttle Bodies 1843 90mm. I'm considering changing my stock OEM for the 90mm. Does anyone have real numbers on the HP gains? do you feel the throttle response as advertised. I have 2016 Dodge Challenger RT Shaker 5.7L any recommendations on throttle bodies, also do these need to be used with a tuner or is it plug & play.
