So last week I was chasing a lean cond. at WOT.
Ended up being the 02 sensor.
Still running the one wire deal,I was running low on time[trying to make the track]
So I installed a AC delco 02.Problem solved-I was happy.
So Im in street trim now with TT chip and pump gas[no alky].
My 02 #'s are like 890 in hi gear?
I dropped the fuel presure down to like 41-42[from 43].I then pulled ALL the fuel out in the chip[20%]
Then my readings fell to 790 in hi gear-and thats ok,but why do I have to pull sooo much fuel out?
Could it be that differnt 02 sensors are like that?Ive never had to pull fuel like that out before?On default it was like 820[with old 02 sensor-same combo]
