In the meantime, you'll notice throttle response change drastically! If you trawl long enough, you'll see Turbo Tom going medieval saying he's tested that on a dyno and yielded no HP/TQ gains. I have a Zetec with an FC 65mm TB and an intake manifold that was dremelled to match up to the TB... that's how I know the differences!
Butt dyno and real dyno are two different things. What you are actually feeling is more throttle response due to the spring on the throttle body having a different tension than the one on the stock throttle body. Other than that, you won't feel any difference in power other than the placebo effect.
