Would you run into any tuning or boost control issues? Link to comment Share on other sites More sharing options...

A couple of people on here don't do that and never seem to learn. Don't be those guys. Lol Edited 16/11/15 12:46 AM by Tocchi Link to comment Share on other sites More sharing options...

Looks like I'll go twin 44mm 1 Link to comment Share on other sites More sharing options...

Or just your turbo (twin scroll) ?Saw an article talking to Kyle at 6boost saying a single gate on a twin scroll turbo is pretty much on par with the twin gate setup on the same turbo Link to comment Share on other sites More sharing options...
