Frequently Asked Questions

Do I need any special tools or automotive knowledge to install?

   No! Unlike other products which require you to cut into your sensors in the vehicle; this product is truly 100% plug n play. It only works for vehicles 1996+ and is tuned for your model. Watch out for those cheap $10-50 mega horsepower products. They are all gimmicks and basically a plastic box with empty space.

Does this product work with automatic and manual?


Does this product work with 2WD or 4WD

    Works on both types if your car has options 

Does this product work with Regular Gas or Diesel?

    Works on both types.

Does this product work with Supercharged or Turbocharged Engines?


Will this product void my warranty?

    No! it will not void your warranty, many dealers frown on any performance upgrades. However, under the law, the manufacturer cannot void your warranty for adding aftermarket parts. The unit removes as easily as it installs. So it can be removed before taking the vehicle to the dealer for service. This is the easiest way to avoid any dealer concerns. 

    (Thanks to the Magnuson Moss Warranty Act: US Code – Title 15, Chapter 50, Sections 2301-2312, your vehicle’s factory warranty is protected by law when you add aftermarket parts.)

How much horsepower will I gain?

    Results do vary and can sometimes take up to 2 weeks to see results due to computer learning. Stage 1 recalibrates the ignition and fuel based on the variables such as the fuel octane, ambient air temp and other sensors in addition to driving style. 

Can this harm my engine or vehicle electronics?

    No, not at all. Zero % chance of any harm. Our products have been dyno tested and proven to work without any bad effects on the vehicle. We guarantee this! 

How does this product work?

    Using your OBD on board computer port - plugs right in - our product modifies signals sent to your vehicles ECU computer. The module optimizes functions such as ignition timing, air fuel mixture, fuel maps and produces more power and better gas mileage. The ECU of modern vehicles controls a series of actuators on an internal combustion engine to ensure the optimum running. It does this by reading values from a multitude of sensors within the engine bay, interpreting the data using multidimensional performance maps (Look-up tables), and adjusting the engine actuators accordingly.

Is this product a resistor?

No, this product does not connect to your engine sensor like many cheap products on the market. No splicing or cutting wires!

Do I need to use Stage 1 first in order to use Stage 2 or 3?

No, Stages will determine how much power you'll able to extract from your vehicle, you don't need to upgrade from one Stage to another.

STAGES Quick Comparison:

 STAGE 1 (FUEL SAVER CHIP) 20HP Increase +16.2 ft·lbs  Up to 4MPG
 STAGE 2 (ALL-AROUND CHIP) 30HP Increase +24.2 ft·lbs  Up to 2MPG
 STAGE 3 (FOCUSED IN POWER) 40HP Increase +32.3 ft·lbs  N/A

    I was a little sceptical about performance chips altogether. But I gave them a chance. I have to say, I'm very pleased ! Definitely see a difference in the shifts and performance.

    Stage 2 Chip for Mercedes 2012 Model W204

    Posted by August R Schubert on Feb 10th 2021

    This chip did something right out of the box. Unsure of exact gains yet but it is doing something. No MPG gain on the stage two but power is noticable. It has been installed and driven daily for 9 days or so. Noticable effects were lower end torque and at the 3.5 RPM point the car pulls significantly harder. 0-60 not much different but 60-100 times is down by 1 second consistantly. I will unplug after the 2 week learning period and retest.

    Smarttune Stage 2

    Posted by on Dec 28th 2020

    So far, had the chip in for one full week and the car does seem to have more pickup. The torque has improved. You can feel that. The MPG is no different. Cannot tell if there is more horsepower. One thing I do notice is the car has a much better feel when the transmission is in comfort mode rather than sport mode. I do not detect any difference in sport mode, but a big difference in comfort mode. So far my opinion is mixed. Yes, I do notice differences and for the price of this chip, the differences are worth it in my opinion. Would I buy this chip again? Yes I would for the price. I'd love to see if there are any difference in the stage 3 and 4 chips. But for now, the stage 2 chip does do some of the things it claims to do.
