    Yes but you’ll see no top end gains- get the map tuner x or deans reflash then you’ll see a difference.

    Those air intake upgrades will change the air flow into the engine, but with the stock ECU tune the engine will not get more fuel to match the increased air flow.

    In addition to generally running the engine leaner, the middle two cylinders tend to run even more lean with the ribbon flame arrestor removed.

    The correct approach is to always match the tune to the actual engine configuration. As you change the air flow into the engine, change the tune to correspond.

    In your case that would be Stage 1 Plus Riva tune to match those air intake changes.
