Over 50 years have passed since JET performance Products started life as an engine building and carburetor shop. At the time, the company was focused on drag racing applications providing race engines and carburetors to local Southern California drag racers. The company also ran many of its own cars in both NHRA and IHRA, which resulted in setting national records in three different classes. Over the next several years the company continued to grow and it became apparent that Carburetor tuning was going to be the companies future as they had become the “go to guys” for carburetors and carburetor tuning. At that time the company was renamed Mike Jones Carburetion after one of the founders and over the next 17 years the company developed and tuned carburetors for some of the top names in Drag racing, NASCAR and Off Road racing in addition to building some of the fastest and most reliable street carburetors in the business. By this time, these carburetors were being shipped all over the United States and Canada.

In 1985 Mike Jones sold the company to the current owner Bryant Seller. An Auto Mechanic, Tuner and Drag racer, the company was a great starting place for Seller to develop new products and grow the tuning business. In the mid 1980’s the automotive world was entering into a new era with the introduction of computer controls and fuel injection in most new vehicles. The way to tune vehicles was about to change forever, no more recurving distributors and re-jettting carburetors, electronics was going to take over the automobile industry. Initially these changes looked like they would kill the performance industry, but change brings innovation and new opportunities. Seeing the opportunity and the challenges in these changes Seller, along with a friend that was an electronics wizard, set out to reverse engineer these new computer controlled cars and trucks to see what could be done to improve the performance. After thousands of hours of research and development the first JET Performance Chip was released for General Motors applications. The Company was renamed JET Performance Products and on the way to becoming the leader in computer controlled tuning technology.

Over the past few years, JET has released over a 100 new applications and a complete new product line, the JET Xcelerator. JET Engineers and team continue to bring new and innovative products to the market and develop products that will enhance your automotive driving experience. Accesspeed is proud to offer JET Performance products to our customers. With our lowest price match guarantee, you will always find the best combination of price and selection at Accesspeed.

Speed Calibration and Speedometer Calibrators

 

Do I need to recalibrate my speedometer?

As long as your vehicle is maintained at factory specs for tire size, gear ratio and transmission, the speedometer should continue to register vehicle speed within this range. If you modify your tire size, gears and/or transmission, your speedometer may need to be recalibrated.

 

How do you recalibrate a speedometer for bigger tires?

Changing tire size is one of the most common things car owners do that can affect speedometer accuracy.  Most modern vehicles can have the tire diameter changed in the vehicle computer, which will recalibrate the speedometer properly. However, if your vehicle does not have this feature, you will need to purchase a Speedometer Calibrator.
