Issue losing power

Hello all,

I’ve got an issue at the moment with my hyandai I30N. It’s 2020 on 75,000 miles. It’s loosing power around 2.5k revs but carries on going to 4k revs where it turns jittery. No warning lights are present and I can’t see anything else which is wrong with the car. This only happens when I put my foot down, but if I have a chilled drive I won’t notice it happen at all!

I had it checked at a garage two weeks ago and there were no codes on this at all and have since done the recall for the fuel pump

Any help would be great thank you!
 
What is the condition of the battery/charge? When were the plugs last done? Do you run a tune? Coil(s) or injectors can cause the issue as can contaminated (bad) gas.
