Custom Dyno and EFI Tuning
Get the power as it is meant to be
Compared to carburetors, Electronic Fuel Injection (EFI) systems have the ability to meter fuel and adjust to varying temperatures, air pressures, and vehicle loads with fantastic precision. In order for it to do it right, it needs help with one unknown - the volume of air that is entering the engine. This is the limitation of both the Speed Density and Alpha-N type fuel injection systems. Until a Mass Airflow (MAF) sensor is adapted to a Harley, a dynamometer and wide band oxygen sensors are the indispensable tools used to educate the EFI with the missing component: volumetric efficiency (VE).
The Experts On High Performance
Get it straight and the results will amaze you
Not just at wide open throttle, but everywhere. Part throttle, cruising, accelerating, idling, uphill, downhill - it always works right. Great throttle response, optimal fuel economy, no excessive engine temperatures, no pinging, no hesitation, no popping, no misfires - these are the results of a properly calibrated fuel management system.
The Speed/Density EFI is the best available. Alpha-N systems simply can not provide precise control over the fuel delivery and the timing in the same way. And no other system even comes close to the fine tuning of each mode of operation that the Delphi system is capable of.
From stock to the most radical builds, there is no better choice.
