Easy solution is to get rid of the soler throttle body and go with a stock LT5. Not the first time I have seen this happen with those...and that was after swapping a NW 103 that was tuned for a Soler 107. Made timing go so far negative that I didn't even want to attempt to correct it in the VTT. But if you want to try and make it work, you need to go into the VTT, uncheck the boxes that applies changes to all, and remove torque in the idle region .20-.30 airmass/ 4-800rpm area and interpolate around that spot for the -10, 0, 10 degree tables. I would remove 20ft lbs at a time until timing gets around 10-15 degrees. If you pull too much torque it will start to act funky. Honestly anything above +5 degrees with a 0-15 zero pedal torque is probably fine.
