Ok,Ok...I know ,search other threads first, and I did, but there are many different answers to this..not much found that is definitive...I've got an '03 GT 4.6, all stock. I'm gonna bet 50% say 19lb hr, 27% say 21lb hr and23% say 21.5!! I've also seen that the ECM makes up the diff between 19 and 21lb hr.:sorry..this can be frustrating!! I appreciate any help you all can give. I need to know to send the info to SCT to allow tuning parameters...and it seems there could be 19's or 21's depending on mid year production???:(...Thanks!! I've got some mods planned and this will help...
