  1. Ok im still new so dont shoot me. I have a 89 5.0 with tfs1 cam, Edlebrock lower and Pro products upper, Cold air intake, Mac lt's, Gt40p heads. Now i have leakin injectors and wanna switch out with a 75mm maf cal for 24lb injectors along with a 75mm Tb and of course 24lb injectors. Will i have to get it tuned? Its my daily drived
     
  2. No you shouldnt need a tune, especially if your car runs fine now and all your doing is a meter and injector upgrades.
