Hi ya, sorry you’re still having bother with this. Just for the record - all connections were checked and you found, no leaks. You also checked the vacuum hose onto the inlet and again, no leaks.
Having mentioned a ‘custom’ remap, how was at his completed? How custom are we talking?What was your air set up at that time?
Logically thinking about this...Possibly, you could be right when mentioning the map... you’ve exhausted every other possibility - basically everything was fine before the ram air was installed... not one other thing has been changed including fuel type or any additives?... just the ram air induction kit?... so that being the case; possibly the map doesn’t like the new air / fuel mixture and is over compensating??
Look forward to your reply on this buddy, hoping we get this sorted!
