Given it a good clean today, was fairly well clogged up. Its solved the kangaroo'ing issue, but still the turbo seems to spool up and then back off when accelerating slowly at around 2k rpm. Would it make sense that if the turbos boost pressure has been increased lower down the range, that the engine is getting more air than can be effectively used, thus causing the engine management system to cut the turbo to reduce the air intake? It only cuts the turbo for a split second then spools up straight away like its inbetween decisions. Cheers
