Dicking around with o2 clamp, what's it supposed to feel like?
 

I haven't really noticed a big difference since installing my clamp. I went out for a drive at .32 and didn't notice huge bogs but I kind of felt a flat spot on tip-in at certain times. I bumped it up to .335 and it felt a little better, and tried jumping up to .35 and I didn't feel any bogs except for one time in 3rd gear at about 3200 on a quick tip-in. Other than that it kinda feels the same as before. I've read some posts that seemed like it's supposed to make some huge difference, so should I just keep leaning it out? I know .47 reads stoich, but how will I know when it's too lean otherwise?

I just need to dump this stock ECU BS and get down to ordering and building my MS.

the only thing is should change is the hesitation between vacuum and boost.
since the stock ecu doesn't want to add the fuel your FMU is dumping in. So the transition becomes smooth as silk.

other than that, it shouldn't make it feel any different. or fix "bogs"

It didn't have any "bogs" before, the posts about tuning just said your car might "bog rich" when putting the o2 clamp in. I guess it's working like it should be, the volts and everything check out, so I'll just leave it as is and take satisfaction in the fact that it provides a safety net :)

yeah, if the voltage is incorecct the fuel can just be too much....

sorry i thought you were trying to cure the car of being boggy....
