Help With Tuning

  1. Hey, I'm new here and need some advice. I have a 88 gt that has a new 306 using gt 40 heads intake upper and lower bbk headers, BBk throttle body and I believe the factory mass air meter. Has a comp cam too, not sure the lift nor duration. Runs pretty strong, I don't think it's been tuned though. Not even sure if it was a original mass air car. It has 24 lb injectors too, is there anything I need to do with the computer in the kick panel?
  2. matching maf for 24s?

  3. A factory Maf is for 19lb injectors, unless you are using a cobra computer and Maf. Otherwise you need a matching "calibrated" Maf or a custom tune
