I'm a bit hesitant though as I already spent money for the Versa tune so why spend more for another tune.
Post here a 4th gear WOT log between 3000 and 6000rpm and let's see what the problem may be.
Log the following:
1. Absolute load;
2. Engine RPM;
3. Mass airflow;
4. actual AFR
5. desired AFR
6. Fuel Rail Pressure;
7. Injector Duty Cycle;
8. Timing Advance;
9. Knock retard;
10. Manifold Absolute Pressure;
11. Wastegate Duty Cycle;
12. Vehicle Speed;
Also remember that the OTS (off the shelf) tunes are general tunes, they are not calibrated specifically for your vehicle. Also, tuning around defects is not a good idea, so your friend might have acquired VT and use it a bit inappropriately, because once you get to know the defect you should fix it.
But let's see what you've got. We can make your car mad...
