Something I was just thinking of. If the sputtering at 14-16psi is in fact detonation then wouldn't the ca18et's knock sensor detect that and go to limp mode? Or at least throw a CEL? Kinda dumb if all it does is kill fuel and/or spark for a brief moment and not even let us know whats wrong.
BTW guys I fiiinaaaly got a T25G. Mayb my car will actually run soon and Jason's vette eater won't be the "fastest S12 in Vegas" anymore. WHA!!!!! OH SHIT!!
