First log and tune with built motor, bad o2??

[Bmxr152]

OK so i got the new evo 9 internals in and running. It runs good but seems to be lagging it a little. I have the boost set to 10psi on these runs creeping to 15 or so.

For now it has a ported 14b, 450cc, hacked 1g maf, along with my mods in profile. The o2 voltage never goes any higher than .70 volts which would mean its running lean, but my Wideband is reading 11.5-10.8 throughout the pull. (11.5 at the beginning- richening up to 10.8)
I attached two WOT 3rd gear pulls and one cruise and idle. BTW the reed switch is bad the the speed sensor is off.

Tuners too!? haha

A lot more traffic here so you should get more responses

Yes sir, im just worried about the o2 sensor voltage reading so low.

I'd be a little worried too. Try and borrow one from somebody local for a few hours and see if its just your sensor. Until then, keep the boost at wastegate pressure and put the honeycombs back in. See if you can get "normal" readings at lower flows... hope its just your sensor
