95 or 98 petrol - what do you use?

[Ozsko]

We measured ran a MK7R on our dyno, made 155kw atw. Nearly 20kw down on the average we see. Owner fessed up to using 95. He was in to get a stage 1 tune, we had to send him away and run through a few tanks of 98.

Different demographic for sure, but if your ecu advances the timing and makes more power, you need less throttle input for the same progress. Noting fuel consumption around town wont really give you the best look at how the fuel makes a difference.

When he brought it back it was up 20kw?
