tC injectors cured my lean condition

[LtNoogie]

I installed a set of tC injectors today to see how they would affect my AFR under WOT boost. Shortly after installing them, I drove around to see if idle and low throttle would be affected. I threw CELs twice for a rich condition.

P0101 - Mass Air Flow (MAF) Circuit Range/Performance Problem
P0172 - System Too Rich (Bank 1)

After clearing the codes both times, the codes never came back. I'm guessing that the ECU eventually learned how to cut back on the fuel to keep the A/F mixture stoich.

First video is of a freeway acceleration with the S/C turned off. I tried to go WOT but there was too much traffic. Even at near WOT, the AFR stayed at stoich and timing was well advanced. The video is not as clear as I'd like and I need to find out if it is the screen capture program or Windows Movie Maker.

Second video is a WOT acceleration with 7lb boost. I used to read a 14.7 AFR while doing this, which many said was bad for the engine. In this video AFR bottoms out at 12.03 on the data logger. On my wideband gauge, the reading is 10.5 or something close. Lean condition is gone when the car goes into open-loop acceleration. While maintaining speed, sometimes the boost levels are from 1-3lbs and put the car into open-loop. You see max rich condition there too.

Don't know why there's a difference in the readings. During DFCO, the wideband tops out at 16, the data logger tops out at 18.

I need to find a lull in traffic and try this again.
