Ok fellas, I did a quick writeup of how to tune fuel pressure off the dyno on the street for best performance. My disclaimer is just dont get caught!

That's great....
Except that, if you push the AFR away from stoich for performance.... the ecu will push it back toward stoich via the Adaptive Strategy (KAMRF).
Kinda wasting time, unless you are trying to get the AFR toward stoich...
The procedure is sound though.

From my experience with motors, stoich being the lowest emitter of emissions, it also seems to provide the best performance for most street cars rather than running it rich. On most street cars rather than running "extra" fuel to provide "more" power I have found that by having the AFR perfectly stoich and sometimes even leaned just slightly it increases the volumetric and overall efficiency of the engine providing the most possible power output as well.
So agreed, this proceedure is for finding a stoich AFR.
