TURBO or SUPERCHARGER?
Turbochargers generally make more peak horsepower because they do not rob the engine of mechanical power to operate. However, superchargers produce more immediate, linear torque at low RPMs because they are mechanically connected to the engine, avoiding the lag a turbo requires to spool. 🏁

People often mistake Memorial Day for Veterans Day because both honor U.S. military personnel.
Memorial Day is specifically a solemn day to remember and mourn the service members who died while serving (especially in battle), while Veterans Day is a celebration to thank all living and past veterans for their service.

Why Dyno Tuning Matters..... Maximized Power.
No matter how many performance parts you add, your car won’t achieve its full potential without proper calibration.
Dyno tuning allows us to adjust fuel and ignition settings to optimize horsepower and torque. At Loper's Performance Center, we’ve seen builds gain significant performance improvements after just a single dyno session.

Benefits Beyond Performance
Dyno tuning isn’t just about power—it can also improve fuel efficiency, reduce wear on engine components, and extend the life of aftermarket modifications. By dialing in the optimal settings, you ensure that your performance parts operate as intended, which can save you money and prevent costly repairs down the line.

🔥🔥 It Looks Like Summer has Arrived! 🔥🔥
As you may or may not know... Hotter air is less dense, requiring smaller jets (leaner), while colder air is denser and requires larger jets (richer). A common rule is to change one jet size for every 20 degree F change in temperature.
