discostig Manual mode ________________________ All day, erryday Donating Members 13,798 Member For: 17y 2m 15d Gender: Male Location: Probably above atmospheric pressure Posted 25/02/14 04:14 AM Share Posted 25/02/14 04:14 AM Mine were giving me a rough idle almost right after getting it tuned at 100,000km (07 BFII). Drove like that anyway for 90,000km and finally changed them in order to go run a 1000m track event Now idles fine after WOT runs and also has a bit more power earlier in the revs. Link to comment Share on other sites More sharing options...

It's increased boost pressure and soft or soften springs that get blow off their seats Link to comment Share on other sites More sharing options...
