I've ridden one with a TRE and didn't notice any difference.
To notice the difference you have to know what it does and how it feels specifically on your bike.
Here is an example from my 98 TLS:
Before Tre: In 1st at approx 3800 rpm it would hesitate like it was running out of gas when I would snap the throttle open. Then it would gather itself and start motoring, slowly.
After Tre: With the same criteria it threatened to flip over backwards like a freaking mousetrap and 2nd gear wheelies were retardedly easy at anything up to 110 kph strictly off the throttle.
The SV has similar resuts but not as violent. When I say snap the throttle I don't mean just open it quick, I mean crack it fast.
The secondary butterflies that this FI system uses probably mute the effect of the Tre on our bikes like they did on my Vstrom. I'll find out this spring when I pop them out and go for a ride.
