Really lean in open loop paging ...NoGo or someone
I had made a previous post and left out I tried tuning the car in open loop due to the huge cam and is a nitrous motor but every time it is in open loop its is really lean .240 mV values on the O2s I ruled out vaccum leaks and have no where else to look. The o2s even stay lean when I give it gas. Ive tried every thing.

Have you tried new o2's?. Does it do the same thing in closed loop mode or do they swing normally? What are your fuel trims like in closed loop?

I have brand new O2's in it ac delcos. The funny thing is, even when I'm in closed loop I max the ltrims at 25% at idle. It does fluctuate when Im driving in closed Loop. Im trying to tune this thing in open loop for nitrous and the good old leaded 116 gas. I went to the track saturday and ran on motor but something is wrong, Lacked power up top badd!!
