afr tuning boost
Go and find a basic book on force fed engine tuning.
When cruising you should be at stoichiometric 14.7 and under boost below12to fight detonation .... it all depends on so many things that universal advice does not exist.
I run at only 5 PSI and the stage 2 maps from Mike result in an AFR around 12.2-12.4, which is on the lean side, I think. Especially with the rather agressive timing maps Mike utilizes.
Do not increase the boost level unless you know what AFR you're at and you are aboslutely sure you know how to play the game. And get the wide band working - it's cheap insurance. My sensor is located around 6" down stream from the turbo. I do not know what the best place is with a stock twin exhaust system.
Kind regards,
