i don't think anyone is doubting the slight power loss....if any. it may not rev faster...however it does rev a lot smoother. that's the difference that I experienced.

i did notice that with the DMD, it did rev a little slower....but its nothing for me to complain about.

I too have a lot of mods to my car. (don't have the fidanza/clutch/quaife combo in yet).
