Um yeah, a VAFC isn't a plug and pray device. It needs to be properly tuned on a dyno. You risk serious engine damage from running too lean.

ACHTUNG! ALLES LOOKENSPEEPERS!

Das automobilen ist nicht fuer gefingerpoken und mittengrabben. Ist easy snappen der springenwerk, blowenfusen und poppencorken mit spitzensparken. Ist nicht fuer gwerken bei das dumpkopfen. Das rubbernecken sictseeren keepen das cotten-pickenen hans in das pockets muss; relaxen und watchen das blinkenlichten.
