Judder on idle when nearly warm

When i start my car from cold everything is normal, no shakes, rattles or bangs, when its fully warmed up its the same. But when it in between and i let it idle it judders constantly, its not the dmf as there was a new one put in 30k kilometres ago, the car has a new pd160 turbo,egr delete, egr cooler delete and pd160 intake, it is also mapped by joe power (the best there is in ireland) to 195bhp, what could cause this annoying judder?
