I recently tuned my 04 5.4 2V with a 91perf from mike at 5star, When I put it to the floor Something sqeaks when the transmission shifts, The shifts feel very firm, Is this just my serpentine belt, or could it be my transmission???? Anyone else experiencing this???

Yep, it's the belt. My tuned V10 did the same thing when she hit 2nd and 3rd at WOT. Kinda cool actually!
