Will I need a re-tune ?
Hey what’s up everyone, I know I’m about to ask the dumbest question but will I need a tune if I replace a iWg75 ( 18psi ) wastegate that’s going bad ? Took my car for a tune about a month ago and the tuner told me the wastegate was going bad. Car still made 400 with the bad wastegate. I really don’t want to spend another $500 for a retune.
