Max YOUR ND Miata Performance! Each of our ND has over 200 runs on the dyno to test everything from headers to intakes (the headers work, intakes really don't) to superchargers and turbos. It must be noted that the ND has the smartest ECU we have ever seen, and it takes AGGRESSIVE action to protect the motor. That means even slight variations in weather can result in the car pulling timing, and it also pulls timing if the temperatures of the car fluids start to spike. As a practical matter this means we see dyno results vary by 20 hp and more with just a mild shift in the weather, or fuel, or coolant temps, etc. If your dyno work before and after a change does not precisely duplicate weather variables and car temps and fuel you are wasiting your time and producing data that is not meaningful.
I just installed the Borla exhaust on the MX5. Sweeeeeeet! Thanks, Andy
I received the Roadstersport II, and I wanted to compliment you guys on an awesome product. The Miata should have these on from the factory. They make a great sound, that is not obnoxious at all. The exhaust also installed seamlessly!!! I will buy all of my Miata stuff from you in the future. Thanks,
