Quick one for any 290 owners. There are days I get into the cupra and drive it hard but it seems very laggy. Then there are other times I get in and still surprises me how well it pulls.

always run on either bp ultimate or 99 Ron so ruled that out. Car is always warmed up before boosting etc.

Really bugs me when it’s not performing. The wife has a new mk8 gti golf and it feels quicker when it’s lagging.

I’ve it booked to go onto a rolling road in the next few weeks to check power.

anyone ever had this issue?

Have you plugged it in to a diagnostic tool to see if it is pulling up any DTCs (fault codes)? I would do this first before forking out on a rolling road

Is the lagging on acceleration only? Or is it jerky at constant engine/road speed?

What about ambient/engine temperatures? e.g. what was the oil temp reading when this is occurring?

A quick checklist for initial things to consider is here:
