Thanks for sharing all the different dynos. I am very surprised to see a 13:1 AFR for a boosted car on this motor!

Also, 392whp SAE for bolt-ons and no tune! That's insane!

Could you post your conditions as well? I am just rather curious.

Once again, congratulations and enjoy the monstrous power in safety! Time to free up the exhaust to pull out more power
The programmed AFR is set to 12.32

The Dynojet sniffer measures at the tailpipe which is post both factory cats and therefore "leaner".

Using a scan tool one would see a more accurate AFR at the primary lambda sensor. All installs are logged and checked to validate target lambda meets request.

Great build.
