I used 2 hard rubber spacers at the pedal myself.

I personally would not openly recommend it to anyone.
Definitely not any non-SVT 2.5L (not nearly enough breathing ability) and like I've said before; "All but the top level modified 2.5L SVT's."
A/F tunability is a must.
I personally showed losses with the 65mm until I added my last round of mods (Headers, EH'd UIM, LIM mods)
I think a highly modified SVT (intake, exhaust, Y, chip, MAF, DH UIM, larger LIM) could show gains with A/F tuning. Moderately modified or under and this will lose power.
Oh the car will definitely feel a lot stronger due to the larger TB, but it really won't be. Last summer I swore up and down it made me feel faster until I tested it and saw it didn't.
After the last round of mods I started with the optimized 65mm on and then went back to the optimized 60mm to test it and I my times slowed down noticeably. I quickly went back to the 65mm & it picked up immediately. It continued to get a little better every day after. I'm sticking with the 65mm now.
