Default Software upgrades T3 V40

Hi, Guys, my T3 had a 18000 mile service the other day and they upgraded various software modules, one of which I believe was the ECU, since then I appear to have lost around 20% acceleration power as it seems to ramp up instead of going for it like a bat out of ****, it was very perky until this upgrade, has any body else experienced this.

not happy now.

We have seen the same complaints here in the Netherlands after service.
It seems they have adjusted some values down and it actually is according to factory specs now.
Believe someone actually had Volvo do tests on the car to validate performance and such.

The behavior your seeing is probably a reduced performance in 1st and 2nd gear...

What you are saying sounds right, I am going to see if I can get it put back to how it was, or pay another company to do it.

The answer you will get from Volvo is that it's now according to specs.
So only option to get back what you had it tuning...
I have however heard similar issues with both Polestar and Rica tunes...

I have MTE tune myself and don't have any issues with the behavior seen

I would go ape, they have no right to alter/reduce the performance of the car you bought without you informed consent i.e not just a signature on the service document.

It is probably a Torue limiter they have put in to reduce wear on the clutch etc, the Focus ST225 (mk2) had this from the factory

Hmm...interesting. Mines not due a service until next July so I'll be watching this carefully.

I'll probably go for a T3 toT4 Polestar around then if available for a MY2014.

The difficulty will be proving it is now slower than it was

I took delivery of my T3 about a week ago. It is MY2014 and I too, have the same observation. 1st and 2nd gear seem powerless and I was wondering what happened to the 150bhp??
What is discussed here I guess answers my question although I am not really happy with it...

1st gear in my car has always felt under powered, until you hit second gear, and then it flies
