How to spot a remap

Hi all, so my other half recently bought a 2015 Leon 2.0 TDI FR 150 from main dealer, she’s really pleased with it. I’ve just taken it for a decent run for the first time, and it seems to be quite a bit quicker than the stated 8.4 secs 0-60!
I’m sure it’s quite common to remap these, but the question is, how do you tell? The dealership didn’t mention anything, but I guess they may not have known. I’m not really familiar with remaps, but I guess there’s no real way of knowing?

As an end user the only way I think would be performance benchmarks.
What have you timed the 0-60 as?
If just using your phone it's probably not very accurate.
According to parkers the 150 is about 8.2 and the 184 is around 7.3

If you have OBD interface you could measure the turbo boost pressure - you would need to find out what the standard 150 boost pressure should be? If re-mapped this would be higher.

You could take it to a remap place, have them download the map and check to see if it's been modified.

or just leave it and not worry.

We used to own 150 ps FR hatch and 184 ps VRS Octavia when based in Germany. Real world 0-60 was comparable (despite c.1 second difference on paper). Wasn't until 80+ mph that the additional torque from the 184 ps car started to make a difference and would pull away on the autobahn.

Long story short is that it's probably not mapped.

The 150 is supposed to be 235lb ft - but looking at this darkside graph the stock 150 (red line) is above 250lb ft.

I though i'd try to compare measured 150 vs 184 graphs - so I overlaid these 150 and 184 graphs from Darkside Developments 'calibrating' as best I could for the hp and rpm axis.
red = stock 150
dark = green stock 184
light green = tuned 150
purple and blue = tuned 184

Above 3000 seems to be the biggest difference. 150 has a smaller turbo - so is probably more responsive from idle which will also 'feel' stronger.

The blue line is torque, red is power. The graph shows 235lb ft, no more.

I was referring to the 'Darkside' graph! Clue is when I wrote - looking at the Darkside graph.

The stock 'marketing' graph indeed shows 235lb ft - as I noted.
