Stange and insane. +40 deg timing "OTS" AWE. Questions
Here is my setup:
AWE RSK04 kit
AWE Tubular Manifolds
AWE IC
AWE Downpipes w/ test pipes
AWE Twin 2
X-1 Intake
MBC stand alone at 22 psi tapering to 20 psi
Drained all the 92 oct. 5 gallons of sunoco GT plus (~ 104 oct).
I had a tuner shop help with logging and tweaking. We had a wideband, but for now disregard what it said. His appraoch was to add fuel (lemmi) and watch CFs (ecux) and overall timing.
We started from 0%, added 3%. CFs went down and timing went up. Added 3%. CFs went down and timing went up. Kept adding and eventually we were at the max +25% and CFs were almost 0 all the way across.
We then added timing in 1.5 deg increments until CFs were about 6-7 max. The below graph is the result. +40 degrees timing.
I am not a veteran tuning so bear with me. My thoughts are that if boost is the same and we add fuel and add fuel and timing goes up and up we should be faster and faster and make more and more power regardless of what AFR says. Is this correct? If not what other factors am I missing?
As you can see my O2s say I am running super rich, however my car loved the fuel and reacted with additional timing. I am just about 110% Injector Duty Cycle too.

Your a clown, the oscillating timing is not a function of weight, your experiment didnt prove squat.
It only shows that a vehicle that has massive weight reduction needs a custom tune to make it run optimally.
