Just thought I'd ask for a little help since there is so much knowledge in this forum. Forgive me if there is a thread on this already but I didn't find anything on multiple searches.
Just installed a Whipple 2.9L supercharger kit, Kooks header back dual exhaust, and JDM tune on my 2014 6.2. Truck has been running flawless for approx two weeks, however I am now getting a buzzing vibration sound right in the center of the dash from what sounds like right under that tray with a speaker in the center dash. It only is present after about 3000rpm and louder under wide open throttle. No loss of power, engine rpm issues, and not audible from the engine bay even with my ear all the way back by the firewall. I have already retightened the supercharger/intake bolts and headers/exhaust bolts. Putting in a boost gauge Friday to see what the boost is doing.
Any ideas or advice would be a great help!!! Thanks y'all.
