I was under the impression that the TRE was supposed to help the Busa in gears 1,2,3 and 6. My brother already took his Busa, no mods to 11000rpm. Since that was without the TRE, that leaves the questions: 1. Does the current TRE work for the Busa? 2. Is it restricted?
From what I understand, you should feel a snappier response in 1,2,3 gears that is noticable. Is that the case with yours Schmud?
Anyone knowledgable on this that can give a definite answer on these questions? I'm going to surf the net for a little while...
