  1. I have an 89 stang with hci and sc with 10 psi, should my stock ignition be ok?
  2. I still run a stock ignition and have been to 20psi. and been 10.30 with it I do have the plugs closed up to around .030 though. But it will not hurt to move up at all and would probably make a bit more power with the S/C and burn cleaner.
