Hey all, know this is an old thread but didn't want to start a new one unnecessarily. I've got an rb25det neo that runs richer than a Bavarian chocolate cake after a 4 course, specs are:
Stock turbo
Uprated intercooler
Uprated fuel pump
Stock rail and intake
3" turbo back exhaust
Just wondering if the rich condition could be because of an undersized return line. Cheers in advance.
