Depends on who you talk to since 99% on this forum say too lean, but can't say there is any data to prove them right. I have been readjusting mine to be in the .84 to .87 range while at e30. My fuel pressure on both low and high side have been good and steady. Inj pulse width based on a log from tonight was 5.7 to 6.1 range. On 93 octane it was 5.0 to 5.2.. My reason to run e30 is the cooling benefit plus being able to get same or better gain and can stop having to add boostane.
