Results will vary. Contributing factors include the vehicle condition, vehicle setup, dyno type, dyno setup, environmental factors, fuel quality, and more. When describing fuels, the North American Region (NAR) uses the Anti-Knock Index (AKI), (RON+MON)/2, or (R+M)/2. The Rest of the World (ROW) uses RON. RON is Research Octane Number and MON is Motor Octane Number.

  • Question

    I have a stock setup, other than an apr catback non res. Will this tune make the exhaust sound better and have crackles and pops?

    By Kevin Johnson on February 11, 2023

    Answer
    When you increase power, more exhaust runs through the system at wide open throttle, so it will change the note of the exhaust, and in our opinion, it improves. The tune does not alter the exhaust crackle. We keep that functionality the same as stock.

  • Question

    Hi, I was planning on doing the HPA RS7 turbos when I do the serviceable oil screen relocation install. Would this tune be applicable for that? I will not do the down pipe and exhausts yet as that requires “stage 2” and don’t want to put extra power on worn turbos…

Acceleration Testing

Dyno testing is a great way to gauge power increases over the entire rev range but may not translate to real world performance. Through GPS based acceleration testing, APRโ€™s Engineers were able to verify increases made on the dyno translated to a faster and quicker vehicle on the street.
