I found awhile back the commanded AFR is a quick and easy fix for old cars using E fuel... works great in new ones too! Instant and accurate fix of LTFT issues because of fuel change.
LOL I HATE those tunes too and in the old days Harris, Z-Industries, JET, Edelbrock, and Hypertech to name a few were all guilty of it. Compare function on Tunerpro is always useful to have when you have a questionable tune.

ABOUT THE ONLY TUNING I WILL DO IS STREET TUNING.....DYNO TUNES ARE HORRIBLE.....The only way to get it dialed in is get it out on the street and load the engine like normal.

My L31 picked up nearly 20 ft/lbs of torque in places with an accurate tune. The only time it saw a wideband or dyno was after the fact, only to see where it was at and verify gains.
