    Measuring tunnel pressure

    https://www.dynotunenitrous.com/stor...?idproduct=130

    This is what I installed years ago and still works fine, you just can't data log from it. Glade Rider is also using this same setup for many years also. We both used a Velcro mount on the glove box, and attached it inside the glove box when not needed.

    Blue works good in sunlight, works with polarized glasses, and get the PWC water resistant version.

    We added the Motec sensor so we could log tunnel pressure.

    Bottom line, install PRVs and it will help with stuffing above 83+/-.

    On the S3 hulls stuffing did not typically occur until above 83 mph and 40-43 psi tunnel pressure.

    I will tell you trying to read the gauge at 88+ mph is difficult!
