If you had a ton of relief, then you tighten the truss rod (less relief)... you've decreased the distance you have to press down on the string to fret it... less distance ---> less tension.
I forgot where the truss rod is adjusted from on the Toronado? Headstock or butt? If it's adjusted at the butt, double check all 4 neck plate screws, make sure they are all tight.
