But if i let off the throttle at all it goes away. Also i checked to see if the sound was there in a different gear at the same engine RPM's but i did not notice the sound. So far i have installed a CAI+scoop, ported throttle, Catch Can and MGW shifter. I have heard sometimes the catch cans can make strange noises. And i know i can hear more transmission noise after i installed my shifter im going to try and rearange the insulation to see it that helps. But any suggestions before i take it in to get it looked at?
I'm sorry to hear of the noise(s) you're hearing while the vehicle is in motion. I'm sure that's a irritating occurrence. I understand your desire to field opinions prior a dealership visit, but please let me know if you plan to take it in. I can schedule the appointment for you and monitor the process. Feel free to PM me in these matters anytime.
