I just bought my LBZ. I had an LLY, but the new engine sounds different when I let off of the accelorator. It makes a sound like the Star Wars Millenium Falcon when its engine didn't work. Kinda like a "ZEOW, ZEOw, ZEow, Zeow, zeow. I know that looks funny, but that's the best I can describe it.

Please tell me this is normal.

Thanks.

Oh, by the way, I love my new "Millenium Falcon"

Traveling through hyperspace isn't like dusting crops, boy!

Is it like a turbo shutter?? My 05 F350 would do that constantly after letting off from heavy acceleration. I have a video on here where it is very evident towards the end. Burnout vid :D (http://video.dieselplace.com/category/Burnouts/0/CB936067-0536-4AB5-BD32-6892BDBAF815.htm)

i started hearing the same sound on my 6.5 after I put on the 4" exhaust.
