It's also fairly poor on fuel (28-30mpg) and compared to my 2004 xc70 d5 163(shark remap,egr delete, stainless exhaust and intercooler) it feel weak especially low on torque. I wonder if being the twin turbo set up that one of the plastic joining feed pipes might have split on the turbos but I cant find any info on it being an issue. Any info greatly recieved.
