I dont know that you would notice all that much power gain. If anything it will smooth out the idle and perhaps help out in the starting dept. But I wouldnt expect to gain any noticeable top end power.

I bought one, my 4.0 with 205k needs anything it could get. As for top end, I don't really see a difference, but I am pushing 14.5" wide tires. But it did smooth out the idle like laneiac said and my engine just plain runs better. If you have the extra money to spend you won't be dissapointed.
