    Ideal Idle AFR.

    Found this article interesting.

    Your target AFR should be around 14.7:1 in vacuum, around 12.5:1 at static, and around 11.5-11.0:1 as you approach your peak boost level. This will achieve the best fuel economy while supporting for lots of airflow.

    Good luck getting that w/ just a RRFPR. EMS would be the only way to get it that perfect

    I get my best holeshots when my AFR is about 14.5:1 at idle. I tried it down to 13:1, but the snap wasn't has good.
