under partial load/throttle I get an exhaust leak noise. I’m used to my last hemi ram pinging under the same conditions using 87 but is that what this noise is ? Or is it the same harmonic you get if you accelerate in a manual car low rpm in a higher gear,(kind of like a shuttering noise) happens around 1500/2000 rpm say cruising at 40 and starting to accelerate. It’s not obnoxious just something I notice.
