If you're looking for top end power, it does indeed make bugger all difference. If they are testing 6th gear roll on, it will make no all difference.
The TRE (Timing Retard Eliminator) is designed to replace the lower power 1st & 2nd gear maps, particularly below 6,000rpm. These bikes have a separate ignition map for each gear, allowing tame maps for low gears to aid emissions and to stop newbs looping out. However, this can cause the bike to be sluggish in low gear mid range. The TRE works by fooling the system into using the 5th gear map for all six gears, thus eliminating the timing retard built into the lower gear maps.
I have one of the more expensive TREs which comes with a gear indicator. There is a noticeable difference in 1st gear, and I like seeing what gear I am in. I have not tried on the cheap versions so can not compare...
