Not greatly - other than the APR tune having more power/torque at mid-throttle. Also going on/off the gas feels smoother with APR but again will see how the tune/ECU adapts and again this is subjective.

I did a 0-100 run the other day and performance from the APR tune was similar.

So unfortunately it looks like both files are putting out similar power/torque on my car - but will get this tested and confirmed on Wednesday.

The hard thing with Viezu tune is that I didn't have much to benchmark against so if I thought I wasn't getting the numbers I didn't know if this was tune related or to look elsewhere.

I have had the diverter valve changed out a while back but it didn't make any difference (though this was on the misbehaving tune).

Sounds like either:

1) 125TSI can't be tuned up to the same level as 147/155 (?)
2) I'm actually getting the maximum power/torque from my car
3) Some other issue resulting in loss of power

But will know more for sure in a couple of days.
