load being that high could mean a couple things.

1. engine displacement scalar is wrong (but I assume you havent changed this)

2. injector values are wrong, this is likely if the load is way off and the MTF is giving good stft's

3. MTF is way too high and the stft are bad

Theoretically 1.0 load is perfect volumetric efficiency, you should never see more than that on a NA car. In fact I would be impressed to see more than .95 load. Unfortunately load calculation is only as good as your tune. I have seen a bit over 1, maybe 1.02 or 1.03 on my logs after I changed injectors, so I just changed the injector slopes and MTF a bit to get it to fall around .96-.98 at wide open.

I'm trying to think if what you are seeing is from too big or too small injector slopes... need a minute on that one. Hopefully it is becoming apparent to you why it is so important to have the correct injector values in your tune, as I have been telling you for years. The entire tune is thrown off when the load calculation is wrong.

Not on this list? Almost certainly crap.
