Automotive Performance Dyno Tuning Services

APITuning.com, with over 25 years of experience, is conveniently located in Yonkers, NY. It's easy to get to from within the NY Metropolitan area. Whether your car is muscle car, a late model, or anyting in-between, a FWD, RWD, 4WD or AWD, API can dyno-tune it. API can even arrange dyno-tuning on a dyno local to you.

API performs non-competitive dyno tunes. There is no reason API would hold back power on your tune since API and affiliates do not build cars that compete.

With the use of our in-house Dynapack now AWD/4WD capable, API gives you a precision tune for maximum power throughout the entire RPM range that includes:

  • Tuned Variable Valve Timing Curve (when the Variable Valve Angle feature is available)
  • Precise Variable Valve Lift switching points (when the Variable Valve Lift feature is available)
  • Crisp Throttle response

You also get the best fuel mileage possible, which makes sense for your daily driver. Many daily driver's savings in fuel costs and maintenance have gotten a return on dyno tuning costs within a few months of driving. 

The time necessary to properly tune on the API in-house dyno is all inclusive so you're not paying for extra dyno time if a tuning session goes a little longer than expected, even on your AWD and 4WD vehicle. In fact, simple adjustments and repairs are typically done without adding to dyno time costs.

A re-tune for any modifications you do after an API full tune will be done at a fraction of the cost of a full tune. The objective is to give you the outstanding tuning experience that others have had with API, which leads to repeat business and referrals.

Performance Tuning Services

Flash Tuning
When available for your daily driver, a Flash tune is the most effective and logical method to take advantage of hidden power and any engine modification you make all the way to extreme power. With the right software mortifications, a Flash tune allows full control of ignition timing, fuel delivery, manipulating the most important injector parameters of models and sizes that meet your application needs, as well as other engine functions while retaining all interfaces to the vehicle, including dashboards, security, and other features interacting with the VCM. Most popular vehicles tuned are shown. If you don’t see your vehicle listed, fill out a quote request and API can help find a Flash Tuning System or if another tuning system is right for you...


Standalone Engine Tuning
When you're striving for the ultimate in performance, these stock ECU replacements are what you're looking for. You can even add a stand-alone to control timing, electronic fuel injection, and other engine functions on earlier model vehicles that don't have an ECU. Standalone's support high grade sensors and manipulating the most important injector parameters of models and sizes that meet your application needs. When you're making high boost power or maximizing an all-motor application with ultra-light parts, you don't want any hiccups that may cause damage or even an undesired dismantling of you engine. Standalone's can be found as plug-and-play for many popular vehicles, or can be directly wired to engine devices with a universal unit and supplied harness, typically replacing the stock wire harness...


Chip Tunes
A “canned” Chip Tune is typically an inexpensive way to squeeze out more power utilizing a stock ECU that accepts a modified Read-Only-Memory (ROM) chip when you’re doing a bolt-on, like intake or exhaust. Software is available for many popular chipped applications so that a custom dyno tune to maximize power, drivability, and fuel economy may make sense. Chip tunes allows modifications of ignition timing, fuel delivery, and other engine functions while retaining all interfaces to the vehicle, including dashboards, security, and other features interacting with the ECU...


Piggyback Systems
When flash software, a stand-alone replacement, or a chip tune is not available for your ECU, a Piggyback (PB) system may be an alternative to extract any hidden horsepower and compensate for larger injectors when there is a need to upgrade. A PB is used in conjunction with the stock ECU. It interrupts (cuts into) one or more signal wires. With a simple PB, by adding, let's say, extra voltage to a map sensor signal, the ECU is "faked" into thinking the engine is making more power, pushing the ECU into that part of the tune. There may not be much margin in a stock ECU for a simple PB to take advantage of, and/or the stock ECU may aggressively compensate, let's say the A/F Ratio, away from your requirements back to factory tolerances. The more elaborate PBs go so far as to interrupt injectors, ignition, and O2 sensor, offering extreme control of ignition timing and fuel delivery. Although the more elaborate PBs require a different tuning strategy, there is always interaction with stock ECU. Dyno tuning a PB system is the best method to maximize power while avoiding "Check Engine" codes, poor mileage and erratic drivability...


Remote Tuning
In some Flash or Chip cases, software packages are available for a particular application, but not cost effective and/or too complicated to master when a tuner finds few are interested. It is sometimes possible to get a custom tune for those applications by organizing a dyno session with a tuner in different location that has the software. Information from the dyno is relayed to the tuner who modifies the tune which is then brought back to the car and installed. This method is typically slow and more expensive than when tuner and software is located at the dyno, and may require multiple dyno sessions, but some enthusiasts have accomplished such tunes.

 


Carburetor Tuning
If you have muscle car, dune buggie, or other carbureted vehicle, we can check it's running within safe specs and maximize the power it puts out. Checking or re-jetting your carburetor for a safe and efficient A/F ratio is a must. We can determine if a mechanical timing curve kit can increase power or if installing/tuning an electronic ignition interface will give you precision performance through the entire RPM range.

API knows how to tune to make your car maximize power safely, so no matter what you drive, it’s in good hands with us.
