  1. I'm still playing with the tune on my '93 GT. I live in Colorado about a mile high. I'm wondering if I need to adjust my altitude spark tables as well as my sea level ones? Thanks!!!
  2. Im no expert but, what I did to make things simple was to set base, sea level & altitude all the same. Since you are at high alt, you might want to set yours up to all eqaul the altitude table instead of sea level like i did.
