    What are your ltfts (long term fuel trim) at idle and cruising? Also pull up your 02 sensor 1 bank 1 to make sure it's reading correctly..it should bounce around. Start there to fake sure you don't have a mechanical problem like a band 02 sensor or a vacuum leak on headers or intake..



    Pic or refrence on what my torque looks like on my tablet,.don't look at the values as I had and issue...but you want your ltft and stft should be + or - 5% at least. Also your pcm is still learning..you shouldn't do WOT runs until a good 20 to 30 mins of light throttle smooth acceleration and long steady cruising speeds in 3rd gear....check your trims while doing this..they should improve, if not there is a mechanical issue.
