Quote: Duner, I am suprised you are killing O2 sensors. I run mine with the brake and don't have any problems. I run mine a little richer to be on the safe side, if that makes a diff. I do plan on leaning it up a bit though next time.
Right now: 10.9 AFR Future: 11.5
Mine picked up a ton by going a little bit leaner. Like 3 tenths and 3 mph worth of picked up! Of course what looked like rich on the dyno ended up being a full point leaner in high-gear on the track. The added load from trying to push a barn door thru the wind meant it wanted more fuel.
I am going to try an entirely different wideband setup…. I could have paid for an entirely new system with what I've already invested in just the sensors.
