ALL DYNO TUNES ARE BY APPOINTMENT ONLY MUST HAVE A FULL TANK OF FUEL UNLEADED ONLY ENGINES MUST BE IN GOOD MECHANICAL CONDITION, CLUTCH MUST BE WORKING CORRECTLY, NO EXHAUST LEAKS, STARTING AND CHARGING SYSTEM IN WORKING ORDER, REAR TIRE IN GOOD CONDITION, CHAINS AND DRIVE BELTS IN GOOD CONDITION, IF ANY OF THESE ITEMS NEED REPAIR WE CAN DO THIS @ ADDITIONAL CHARGE
IF YOU WANT TO TUNE WITH RACE FUELS YOU WILL BE CHARGED FOR WIDE BAND 02 SENSORS THEY WILL BE YOURS TO USE ANY TIME CHANGES ARE MADE IN YOUR ENGINE COMBO AND NEED RE TUNING
A Dynamometer is essential to realizing the full potential of today's fuel injected and carburated motorcycles with performance modifications. This is the only tool that can accurately calibrate fuel and ignition maps or diagnose run/drive ability issues in a controlled environment. We have technicians that are trained to tune H-D Race Tuner, pro tuner, Power Commander, power vision std and pro (Delucca Racing Engines is a certified Dynojet tuning center) and have experience with many other aftermarket tuning devices. with over 45 years in building performance and racing engines for all types of racing we use that experience to build engine combinations
that will make the difference 90 percent of the time we find on a high performance harley build that just dont
make the power it should or dont last is the wrong combo of parts bad out of spec machine work and poor assembly add this all up with a quickie dyno tune and you will have junk in no time a good tune takes time

Understanding fuel and ignition requirements on a performance or racing engine comes with years of
experience all engines will not need the same tuning air fuel ratios or timing to make max Torque and HP at full
throttle at max load you will NOT have a flat line AFR from above idle rpm to max HP rpm





The simplest way to look at the internal combustion engine and understand what is done to increase performance is to see it as an air pump. The more air it is capable of pumping at any given time, the more power it will make (expressed as Volumetric Efficiency or VE). To get the most energy out of that air relies on accurate metering of fuel to that air (expressed as stoichiometric, an AFR of 14.7:1 is the theoretical ratio that results in the greatest release of available energy in gasoline). Real world inefficiencies result in an air/fuel ratio (AFR) of 12.8:1 to 13.3:1, for best power and 14.5:1, for best mileage.

The VE, AFR and tuning requirements constantly vary as determined by the mechanical and dynamic properties of the engine. The main mechanical parts are typically engine size (volume), compression ratio/cylinder pressure (static, corrected and dynamic), cam timing/lift, port/valve flow capacity (cfm, including the induction system), exhaust and NOS/super/turbo charging.

The exhaust system is the largest, single, variable influence on how the motor processes air, the shape of the VE graph and tuning requirements. The dynamic parts are typically RPM, throttle position and load (including wind, tire pressure, terrain, gearing and luggage).

Ignition requirements are dictated by engine design properties such as exhaust (how much heat is retained), cam profiles, piston/combustion chamber shape, piston/head clearance (quench/squish), cylinder pressures, rpm limits, fuel quality and intended use.

On carbureted motorcycles to adjust air/fuel ratios we use Dynojet recalibration kits. To install we remove the carburetors to gain access to and replace pilot jets, main jets, emulsion tubes, needles and make float height adjustments.

This procedure can require removing and replacing the carburetors many times until the correct ratios are accomplished. A dyno tune is the most efficient and accurate method.

Fuel Injected Motorcycles have throttle bodies and fuel injectors driven by the ECU (engine control unit) and its programming or calibration. Input from a variety on sensors allows more accurate control as engine demands change and offsets to account for environment changes.

DRE cycles Should stand for "Doctor of Engine-ology" Mike Delucca and sons have saved me and a few friends from the despair of throwing money at these bikes to make them fast. I brought him a basket case (box case) harley motor and he turned it into a high power work of art. I told my buddy (who'd just spent $3000.00 in parts on his bike) who was unhappy with the performance of his StreetGlide to "take it to DRE". Mike interviewed him to get a feel for his riding style and weight. "Do you usually ride alone or with someone?" He then spent countless hours dialing in every throttle position, and when he was done the anemic bagger was a "Beast"!! They are the "Guru's Gurus"
