went back out looked again now maf was not reading like that but my ltftb2 was -100.0 wtf is wrong with my truck
post log files and the tune if possible.
What year truck is this? I did a tune on a 98 firebird that had the same problem and it was because that year the pcm only supported a certain number of PID's, like 24 I think it is. Maybe its something similar to that
does it have a B2S1 o2 sensor? If not, then that is your problem. I think the V6s do not have it but the V8 should.

Ive attatched my latest scan that i did this morning to work, all was good till a left from a stop towards the end thats when everything flatlined and truck went lean then went rich.can someone point me in the right direction
everything looks good to me. I am assuming that you are boosted, so the heat from a high throttle run could have caused the o2s to do weird things. Other than that, I see no issue.

yes i am FI during that scan i didnt run hard just left from a stop sign and everything went lean. is this normal? thanks for helping me!
you left hard enough to go in to boost, so that was just my guess at it as the rest looked normal.
