  • Question

    Hello, Is this Tune software pre-tuned for an Intercooler? I have an intake, a catback, and I'm looking to add an intercooler but I know that changes my Air-Flow-Ratio. Will I need to re-adjust my Stage 1 tune for an intercooler or is the Stage 1 tune here already ready for an intercooler?

    By Michael Esposito on March 14, 2023

    Answer
    Intake, intercooler, and catback are all plug and play with our tuning.
