runs lean in drive

[JsLs]

Hey guys I'm new to the forum and would be grateful if anybody could help me out with my problem. Just finished up the h/c/i swap and bought hptuners to try tunning the truck. The truck idles in park and neutral fine but every time I put it in drive or reverse it goes extremely lean and wants to die on me. We chased down a vacuum leak at the injector o-rings but that wasn't it. I just can't seem to find solution for this . Has anybody had a similar problem?

-AEM Wideband

Thanks in advance!

Are you running o2 sensor with this setup at all? They aren't disabled in the tune and that log file shows them not working.

I didn't dig into it far but the commanded AFR jumps to 17.0 when put in gear.

O2 sensor are installed but I have it in open loop. I am using the aem wideband in place of B1S1.
Thanks for looking.

Cam swaps (on any cam worth installing) jack your low
end VE (pumping efficiency) and you need to make the
tables match the new reality. Right now your old table
is saying that more air is taken in, than really is. That
makes mixture shoot fat. And the air that blows through
the overlap bends O2 sensors to read lean, so you trim
fat as well. And with all of this you need more air to idle
(higher MAP) so you pull timing which helps none.
