Fair point.
I guess these things are relative.
You see, in my mind, anything less than about 220bhp/tonne doesn't seem quick, but then again if that's not something you've experienced than any improvement in a mundane car is going to feel good.
That comes across as a bit arrogant I guess, but that's where I am. CBA with cars any more, no fun on the road to be had (far too stressful and all I end up doing these days is wishing I was on my bike) and had my shot at tracks/racing.
FWIW mort, having been around car forums a lot in the past, my understanding is that some diseasels are "off the boil" out of the box so to speak, as they are not designed to be anywhere near the limit. A bit like some of the lazy V8's the American car market used to produce.
I had a Jag XJV8 Sport, it was one of the most beautiful cars to look at, but even though it had a V8 lump.........it just didn't have any get up n go, lovely for cruising and burning a gallon every 20mile but that was it, white leather and black wood interior..........still very nice to sit in, but it didn't have any go about it, so me and Babytiger decided to chuck it in for something other than a Jag..............came out with a 2.1 X-Type....

worst buy ever, the V6 did sound lovely but produced very little BHP for the high revs, simply supped as much petrol as the V8 for less power, I was now thinking, modern Jags are not worth the money, so went back to Saab, quick standard, remap to stg1 and you have a car that will outrun lots of the modern sports cars, mine wont as its a convertible and its horrendous on the twisty bits, but on a straight road it will get to 60 in less than 7 seconds...........90 before 10 seconds............its very quick off the mark, yes its a full pressure turbo but it is 16 years old too
