What are the disadvantages of tuning a car?
Tuning, even when done right, has downsides. The increased performance might mean your car needs more frequent maintenance and premium fuel. There’s a risk of voiding your warranty. Some tunes might make your car non-compliant with emission standards, leading to legal headaches depending on your location. Cost Effective: Tuning a stock ECU is often once of the most cost effective performance upgrades you can do. Good Performance Improvement: Many stock ECUs have a range of aftermarket tune options which have proven performance benefits, meaning you won’t have to guess if doing the tune is going to be worth it.
