Haven't had a chance to do the log yet, but I can say that the car is much more peppy compared to no bypass tube, and my real-time observations of the afr readout on the LM-1 put the afr at around 13.2:1 in the 3000-5000 rpm range. As a bonus, it seems that the engine stalling issue I've had since installing my 5MT has been somewhat reduced since I installed the bypass. The only negative that I can see so far is that idle is loppy when the motor is cold. The loppy idle is caused by fairly large swings in the afr. I can watch it swing from 13.5:1 to 15.5:1 during cold idle. It doesn't stall though. Just loppy. On a side note, this leads me to conclude that the MAF does play a role in controlling idle, and going to a larger tube may result in a very uneven idle even when the engine is warm.
Anyhow, I'll try to get a log tonight.
