Same here - got my TA new and didn't notice any change in performance or economy as the miles increased.
TA's are VERY tight and grumbly when new. Mine took until about 12k miles and an oil change to feel right and it's totally different now compared to when new.
but the OP's twin air will be VERY tight at on 400 K,
it'll take 10 THOUSAND km to free off fully
The TA does take quite a while to free up.
The first time I noticed that the TwinAir in my current 500 was awakening, was also the first time I heard its loud TwinAir "growl", as if the "beast" was finally unleashed. Unfortunately I didn't pay attention to the odometer reading at that moment, but I think it was already beyond 1000 km.
To me my TA85 drives the same now (at ~3500 km) as it did the day I bought it, brand new.
What could be the cause of these opposite observations?Same here - got my TA new and didn't notice any change in performance or economy as the miles increased.
AutoItalia just proclaimed the 500 TA 105 Sport as the unlimited 500, including the Abarths
Sorry, ultimate....autocorrect fail...lol

Be thankful that FIAT didn't put much effort in reducing the CO2 emission of the TA105. In my country FIAT sells the much heavier Punto with TA100 and an impressive 88 g/km CO2 emission. Compared with that the 99 g/km CO2 emission of the 500 with TA105 seems ridiculously high.But still thinking the voids at some rev are because some freaky chip configuration to cope with emission standards
Do you notice ESC (that is how FIAT calls ESP) when driving normally? What do you mean with "and so"?I fell that if you drive without the Esp and so, the engine works more "clear" with less electronic buging.
My missus bought a 105 500S brand new in February and it displayed this hesitancy in both sport & eco. I thought it just needed running in. It's now done over 2K miles and it still displays this hesitancy at low revs.
I'm sure it's not the good old fashioned turbo lag. For example when idling if you tap the throttle very lightly and quickly the engine acts weird as if it's about to stall but doesn't
She normally fills the car completely (at Tesco) every re-fuel, but recently I just stuck £10 in at the local garage and after that it went brilliantly. Night and day difference. It felt like it had been re-mapped. So she filled up completely at the exact same 95 RON pump but the hesitancy is back. I'm wondering if when I put the tenner in they had 98 RON in their tanks by mistake. Anyone else tried super unleaded in the 105 TA?

Try a partial fill again. Could be a fuel tank breather issue.
I've never driven a 105 but have a normal 85, I've read that the 105 has all the characteristics of the 85 but the quirks are exaggerated so maybe it's behaving normally as such and you need to get used to it ( I'm sounding like a fiat dealer now lol) but 2k is still very low mileage, mine really only loosened up at around 12k and an oil change. Might be an idea to pop in to a dealer and test drive another 105 and see if it's any different, maybe it does have a fault. Re petrol, I recently changed garage/supplier and noticed the car is much smoother and grumbles along happily now at very low revs in 5th, it's still 95 RON fuel so maybe there's less ethanol added but it's definitely smoother but not necessarily any quicker, it has 15k miles up now. I think it's worth spending the extra few cents on decent benzine for a TA!
I have an 85HP TwinAir now 15 months old and 13,000 miles.
I remember the disappointing spluttering at low revs in second gear, lack of torque and revs limited to around 5000 when I first got it. I abandoned Eco mode for all but town driving as on the open road, the lack of acceleration and having to change down on not very steep inclines when below 50 mph meant it just slowed down with your foot down in fifth in eco instead of maintaining speed.
It's now running better than ever - 52 mph on average, when in the high forties to start with. It still gets some getting used to having to change to first at most junctions as it won't pull away safely in second at under 5mph.
Revs are limited to around 5,750 rpm now.
