The biggest difference is that I give my cars hell on a daily basis and the other car (a mates) isn't driven as hard.
The IC will make a big difference as will the mufflers (probably more than the IC) but there's more to the equation than just 'dyno chart' compares. ;-)

Hey cpitts (assuming the same as Lib ASN),
I think with regard to driving that you could put Dave's and mine in the same "like it's stolen" category, both our cars have/had the same number of Km's, no tyre pressures to worry about as it was a hub dyno, almost exactly the same time of year for the tunes (albeit a year apart).
I do agree that the dyno is only a tool of relative comparison rather than absolute measurement but discussions are bound to appear discussing "why is your power less . . ."
Hope life and your Lib is treating you well.
