Just start with that because I am sure the misfires will start shortly after lol
Yeah, the problem is that the diverter valve set up is $500+
Are there quieter BOV set ups or is there a way to quiten a BOV ? I saw someone posted that they used a hose from the BOV down into a wheel well as a type of exhaust which worked quite well - I just want to avoid the "Psschhh" every time I let off the gas.

As for misfires, do you mean as a result of tuning to stage 2 or as a result of the BOV or diverter set up ?
I just replaced the plugs, should I expect to have to replace the coils and/or injectors as well ?
