More Power?

[pdxhummerguy]

I appreciate the input guys. I am not expectig the same performance gains as on my 7.3 psd. That thing is a beast. I would just like to see some improved performance be it ever so slight. i think even another 50hp would help a great deal. Does that exhaust from rubber duck give that nice clear crisp turbo whistle? The ex has that and I love the sound.
