Deville

The Cadillac Deville is an iconic luxury vehicle, known for its comfort and power. And with the right upgrades, your Deville can be taken to a whole new level of performance. Performance chips and ECU tuners are an easy and cost effective way to gain additional horsepower and torque while boosting fuel economy at the same time.

First off, let’s look at the Deville lineup. There’s the classic 1960-1964 Deville series, the 1970-1979 Coupe de Ville, and the 1982-1993 Sedan de Ville. And for the true power seeker, the 1989-1999 Northstar-equipped Deville can really roar when the performance chip is properly tuned.

Performance chips, or engine management systems, allow the owner to increase the vehicle’s horsepower and torque without adding costly components like larger exhaust systems or turbochargers. The engine is retuned for optimal performance, often resulting in a gain of 15-30 horsepower. Tuners also give the option of increasing or decreasing fuel economy. In the Deville, this could equate to better than 30 MPG in the city and up to 45 MPG on the highway.

But performance chips are not just about added horsepower and torque. They can also enhance the vehicle’s throttle response, shift timing, shift firmness, and acceleration curves. And they can be programmed to optimize the engine’s performance to match any set of aftermarket modifications, allowing owners to get the most out of their ride.

In short, performance chips can be a great way to take your Deville to the next level of performance, giving you increased horsepower and torque as well as better fuel economy. Just make sure you select the right chip for your model, and don’t forget to keep an eye on maintenance, so your Deville will be running smooth and fast for years to come.
