Lack of power / lumpy when cold

Hello there everyone,

Just wondered if anyone could give me any advice on what's wrong with my 2.0tdi Mk6 10 plate mapped to 185bhp with an EGR delete.

The car starts absolutely fine but if I get much above 2500rpm before it's fully warmed up there is a serious lack of power and juddering - sort of feels like it's short of fuel.
Below 2500rpm it's absolutely fine and once it's hot its fine.

Always run it on V Power and service every 10K.

It's only does it on a cold morning - probably below 5C.

Any advice would be much appreciated before I start playing with things.

Many thanks,

Davey.

Ready to race!
These cars have a "limp mode" that cuts power at a certain rpm to prevent damage when something is detected wrong but still allow you to limp it home.

Do you have any dash lights or indicators on? Did you scan for codes?
