Go to the track and kick some ass. My 1200HP big chevy acts like it's unhappy on the return road at part throttle after a 7 second 184 MPH pass.
I used to let that bother me and I would tune it away, but by the time I get the intermediate circuit tuned perfect to prevent the burble, I would change the jets for weather and the cycle begins again. Who gives a crap what the engine runs like on the return road as long as its running back to the pit on it's own power? You know what I mean......
