  • 3.4L's with cutouts!...help :(

    Well for the first week my car ran great. Now it is starting to backfire like a MOTHER..I mean like POPOPOPOPOPOPOPOPOPOPOPOPOPOP!

    seems sometimes liek it is hurting the performance. Is this normal or do i need to tune something up?

          Update.

          When I am going 50 in OD (it think it's OD). If i give it 1/4 gas it was stay @1500 and sputter like there is no tomorrow...Makes me guess it is wires or plug related. Not cutout (Thanks Tiago)

          Anyone have any other comments.

              Is your cutout installed before or after the cat? How does yours sound at WOT? I'm considering getting one.
