75mm throttlebody ?

Need some advice. I have a 1999 f150 4x4 with 3.73 ratio gears 5.4L. I have put a flowmaster 50 series, 3 inch y back, superchips programmer, K&N FIPK and throttle body spacer on this and still looking for a "little extra" power for pulling my MX trailer. Thinking of buying the MAC 75mm throttle body.... any suggestions from people that have this? Is it worth the 130 that it is selling for on ebay? Would it add low end power? thanks in advance.....

They seem to help on the Mustangs, I've never tried one on my truck.
