Who is running speed density and no O2 Sensors?

The meth thing is pretty interesting, I've never heard that but I see how that could work. Then again a 2 step dumps raw unburnt fuel straight into the crossover. I myself run pump gas all the time but when I go to the track I use straight C-16, I have only replaced the sensor once since I bought my LM1 in 2006. Keep in mind though you can do a "free air calibration" with the Innovate Wideband Controllers to keep things accurate.
Yep I was on the two step when the meth came on at about 3000rpm. Loaded it up bad and wouldn't run right until the o2's were unplugged and new spark plugs were in.
I think my PLX wideband does that everytime I shut the car off with the battery switch still in the on posistion. It will go from 14.3:1 to saying lean, then after it sits at lean for about 10 seconds it says air.

Matt, there's NO WAY I would run speed density after tuning and being involved with all the setups I have.
A friend who owns a shop has his car over 1,200HP with a MAF and drives it EVERYWHERE with no issues.
I've ran speed density on mine for quite a while and recently switched back to a MAF. The difference in response and keeping the tune where I want it is night and day.
Unless you plan on screwing with the tune all the time, keep the MAF and 02s
