hi. my friend just recently added an rh to his 07 civic si in addition to his cai. the problem is that he feels barely any gains from it. and also i drove his car and its feels as if the rh was never there? and clues? i have a 06 S with a cai and we are dead even, we were dead even, even before he got his rh. he didnt get a defouler yet could this be the problem? and also he reset his ecu already.
