[101Volts]

I suggest you accelerate slower and keep the load on the engine low; If you have a ScanGauge II or other on-board gauge this is easier/quicker to learn. Try to keep the load under 20, 15-20 at the highest (Though YMMV depending on the vehicle, I'm basing this on the Caravan I drive.) You may also attach pizza pans to the hubcaps though they might start rusting quickly if not painted. Also, 50 PSI may or may not be the most fuel-efficient tire PSI for your car; It may be best to test the FC for various tire pressures.

Edit/Update: Find what works for you and your car and locality while staying safe.
