There are quite a few odd things in this tune mostly in the DTC area.
Can you confirm if the "base" tune you posted is the actual unmodified stock file? If not, can you post it?
Some observations
- The MAF values were modified, yet the MAF is set to fail if above 1hz and below 1126hz. The MAF DTC's are set to No MIL.
- There are several DTC's changed to "non-emissions" including U0073 "Control Module Communication Bus Off"
>I don't if they changed these; but I would compare them to the stock values to make sure.
- Some of the TCS options were turned on; yet the tip in torque values are maxed out.
> Once again compare these to stock to confirm. I would leave these stock.
- The injector Flow Rate slope is completely different between the two; yet both reference vacuum.

It's up to you I would consider asking for a refund and trying another tuner or building your own tune since you already have the software (or is it Autocal?)
