Unlock the "Precision Crafted Performance" Hidden in Your Acura

You drive an Acura because you demand a blend of reliability, luxury, and spirited performance. But the reality is, whether you are driving a TLX, MDX, RDX, or Integra, factory ECU settings are designed for the average driver—not the enthusiast. They leave power on the table.

It’s time to claim that power back.

The Stage 4 3-in-1 Performance Module is not just a chip; it is a comprehensive cockpit upgrade. Utilizing next-generation 800Hz CPU processors with AI-driven logic, this device actively optimizes your engine's parameters in real-time. The result? A smoother, more responsive ride with the power you need to merge, pass, and enjoy the road.


3 Powerful Functions in 1 Device

Why settle for a simple tuning box when you can have a complete performance ecosystem? This Stage 4 unit combines three essential tools for the modern Acura owner:

1. AI-Driven Performance Tuning

Powered by our latest "TUNED Performance Logic Plus+" technology, this module safely increases your vehicle's output.

  • Boost Horsepower: Gain up to +50 HP (depending on engine/mods).
  • Increase Torque: Experience up to +25% more torque for faster acceleration.
  • Smart Adaptation: Custom programmed for your specific Acura model and engine type (Turbo, Hybrid, VTEC, etc.).

2. Live Data Cockpit Display

Transform your dashboard into a race-inspired cockpit. Stop guessing what your engine is doing and see it in real-time on the high-contrast display.

  • Performance Metrics: Monitor 0-60 times, braking performance, and G-Force.
  • Vital Stats: Keep an eye on Coolant Temp, Battery Voltage, Live RPM, and Fuel Consumption.
  • Trip Computer: Track trip mileage and drive time accurately.

3. OBD2 Diagnostic Scanner

Save hundreds on mechanic fees. If your Check Engine Light comes on, use the Stage 4 module to read the code immediately, understand the issue, and clear the code on the fly.


Why Acura Owners Choose Stage 4

  • True Plug-and-Play: No cutting wires, no soldering, and no greasy tools. Connects directly to the OBD2 port under your dash (usually near the kick panel).
  • Safe for Your Engine: Unlike cheap "resistor-in-a-box" gimmicks that trick your ECU and can damage wiring, our module works with your car's safety protocols. It leaves all factory emissions and safety limits intact.
  • Warranty Safe: Don't be. Simply unplug it before service, and your vehicle returns to stock instantly. Protected by the Magnuson Moss Warranty Act.
  • Universal Acura Compatibility (2008+): Works seamlessly with Automatic and Manual transmissions, as well as VTEC, Turbo, and SH-AWD systems.

Frequently Asked Questions

Will this work with my specific engine type?
Yes. Whether you have a Turbocharged Type-S, a standard naturally aspirated engine, a Hybrid, or a Diesel, the AI logic adapts to your specific engine configuration.

Do I need to buy Stage 1, 2, or 3 first?
No. The "Stage 4" designation refers to the processing power and feature set (Tuning + Monitoring + Diagnostics). You can jump straight to this unit to get the maximum capability immediately.

Does it drain my battery?
No. The device features a smart "Auto On/Standby" mode. It powers down when you turn off your Acura, consuming little to no power while parked.


🔰 100% Satisfaction Guarantee

We are confident in the performance of our AI Tuning technology. If you don't feel the difference or aren't satisfied with the data features, simply return it for a full refund. You have nothing to lose but the factory restrictions holding your car back.

Ok, I got a 2017 QX50 AWD 3.7l.

Just installed the unit and so far so good which is why I rated it a 3. Now I will update every few days and inform the noticed changes and re-rate the unit.

2008 Altima Coupe 3.5 manual
PLP “Stage 4”

Device is amazing. You can set alarms for your coolant temps, battery voltage, etc. This prevents relying on the sometimes misleading gauge cluster. It warned me of a failing alternator and rising coolant temps before my dash told me any useful info. Throttle response is great, power feels meatier in the mid to high rpm range. If you buy this, don’t expect results on a stock car. This particular tune is best with both intake and exhaust bolt on. Anything more than bolt ons, I would look into something more advanced. If you have anything less than 50% bolt ons, you will mostly be paying for the digital information read outs. 10/10 would recommend, I’ve owned it since New Years 2025.

I purchased a stage 4 performance chip and it’s great. The new edition is even better. Don’t think twice this is the chip you need. Once I plugged up the module and my car instantly became more responsive and it don’t hesitate accelerating. In fact my car reach higher speed and a lot faster. Thanks Performance Chip Tuning your customer service roc as well!!!

Unbelievable difference!

While I've only had this in my car for 3 days, the added performance is incredible! From a dead stop to a slow moving start the wheels bust loose, which they definitely didn't before! It's great to have peace of mind to be able to keep an eye on all of my fluid temps and the alarms that will warn me if something is wrong. I am so glad I bought this stage 4 performance chip for my Buick Regal! Thank you!

Stage 4 performance chip module 0BD2 +LCD

Great product I can already tell the difference in my car there’s no more lag, fast acceleration more torque more horsepower. The only thing is the monitor could’ve been a little bigger

FOR SUBARU 2015

I bought this performance chip it shipped pretty quick. had voltage screen. contacted the company, they walked me through on how to factory reset it. Had to reset it 4 times, but my screen reset and homescreen came on. It happens on some vehicle models, but factory reset is the fix. Works well, I love the code scanner feature too.

Better MPG

After talking directly with someone to get my order out. I got it just in time for my Galveston trip and got 2-3 mpg better even after adding 3/1 level lift and 33’s Nitto’s. Worth the money- Jason

Plp+ performance stage 4

Put it on the Dyno and gained crazy HP I have no super charger, no turbo, no nos. just a intake, cat back exhaust and a E85 conversion. I made 418hp from 378hp. Mind you this chip is paired with a injen pedal pro X throttle controller that paired with this performance chip added crazy HP. I got my car as fast as it can go with out a power adder

Disappointed

I have had the product for just under the two weeks it said it would take to work. However, I have increase in horse power and I have seen of a increase in gas mileage. Im hopeful that it works.

Does not meet expectation/Poor communication

Before placing this review I attempted to contact the company a few times via phone number online was told that I was calling outside of business hours so to contact via email. I sent an email about 4 days ago still no response I purchased the stage 4 performance chip with the monitor I do notice some changes in performance a little bit better of a response from the pedal unfortunately the monitor is not performing to expectations it does not display my MPH, RPMs anything like that all I’ve been able to get is the voltage so I contacted the company to see if there was something I did wrong or maybe if there’s a timeframe they can give me for it to work properly I still have not heard back hopefully I can either exchange your product for just a stage three being that I don’t need the monitor at this point if it’s not going to perform as expected or a partial refund being that a major piece of my purchase is more like a paper weight

It's ok

I was hoping it would turn the auto stop off. Gear changes are smoother and seems to have a little more power.

Unsure

Not sure yet if this product is working. I haven't noticed any improvements as of yet. It does say "tuned" on the display when the vehicle is on, but there's no way to tell if that's the case. So far it seems it's only an obd2 display.

I can say that the included screen is nice and displays important information and is small enough to mount anywhere.

I'm hoping that it's working so it's not wasted money, and if it is, I can then update my review.
