Please help with LS1 rich condition

[Finnish Fireball]

MAF is stock and in stock location, BOV is not open, I have Prochargers own signature BOV in shelf and that one has some built in leakage. I thought it was faulty... I'll put it back now.

Our weather has been exceptionally HOT for ten days, the trims could actually be pretty close when it gets colder. I was thinking that maybe some ignition timing was pulled due to heat and thats the reason it felt slow.

I'm not familiar with airflow frequenses and MAFs, but above 5000 Hz it is red in the log ( MAF LTFT + STFT table).

I'm talking about down low where it's damn near double what it is stock.

The BOV should be wide open at idle. If it isn't, that's why the numbers are so high. Need to fix that and retune.

Good catch, I changed the BOV and test more tomorrow. Thanks Ed.

If with the new BOV it isn't open all the way at idle (alot of them won't without modification) if it's the big "race" style BOV, you need to take it apart, take the spring out and cut a loop out of it.
