2016 Ford F-150 in the shop for an On3 single turbo system featuring a 76/75 turbo.

The customer requested a Boss 302 intake manifold to support stronger high-RPM airflow and complement the turbo setup. Our team completed the installation with minor modifications to the supplied aluminum piping to ensure proper fitment and performance.

If you’re looking to add boost to your daily driver, weekend cruiser, or track build, we’d be glad to help. Send us a message to get started.

Race season is almost here. 🏁

This MK2 Golf GTI came in before SCCA Driver’s School at Summit Point for a full check-over and dyno session. A few small adjustments later… we picked up nearly 30 HP — going from 86 HP to 115 HP.

That’s the difference proper dialing-in makes.

If you’re heading to the track and want every bit of power — and peace of mind — dialed in, message us to book your dyno session.

Not only is a dyno a great tuning tool, but for us it is also a great diagnostic tool! This week we had a 1996 Cobra Race Car come in that was down on power and with a quick dyno session, we found the fuel pressure to be inconsistent. After replacing the fuel pump, we were able to verify our fix and restore over 90hp to this track monster! Not only does a UM dyno session make power, but it also can save your engine!

This 240sx with a 6.0L LS swap came in needing a new tune for an upcoming drift event. We started at 465Hp/452Tq and ended up pushing it to 480Hp/462Tq with our custom tune! That's a gain of 15hp and was able to improve drivability.
