mk2 Posted December 30, 2020 Report Share Posted December 30, 2020 There's no advantage changing anything (other than block EGR and add a sump gas divertor), as the turbo limits the max boost you get. Even if the air filter is old and blocked... For any significant gain you need to remap. 1 Quote Link to comment Share on other sites More sharing options...
