Passed the info on to my dealer, GM has sent a bullitan out regarding the issue and reprogramming the fuel pump seams to fix the noise (I HOPE). I had mine done about 2 weeks ago, but I have been out of town off and on since i had it done so I haven't really had time to test it out. I plan on putting on some miles this weekend so we will see.
Thank again for all the help!!
