I have noticed before the EZ that the TST on 5/5 and up it would have a surge of power at about 1/2 throttle (but I do have an aggressive program), then unload with boost spiking way up then slamming back down. With the EZ it smooths this out, gives me more bottom end, more power with about the same in EGT's. But I think that the power surge I see could be damaging to turbos because of the chuffing. So maybe this could be better on the stock turbo than the TST alone? I dont know if everyone experiences this because I have an aggressive TST and a SPS 66 turbo. But it might be something to concider as long as your boost pressures are kept under control.
