the ecu can't do this alone because there is no a/f sensors of any kind. And honestly, in order to get optimal performance anytime you modify the air intake, whether it be removing the filter or upgrading to a hi flo, you'll never get the full benefit it it's not mapped properly. guys run either bmc or k&n, either filter is superior to an oem filter as far as flow goes, but keep in mind, more flow does mean LESS filtering.
and we are not sponsored by them or any air filter company.
