I think its probably easiest to say by copying and pasting the comments from anothr TTRS owner with a revo map and cat by-pass pipe, with hard figures from his vbox!
"Any way I have a GPS meter, the same as EVO use to test the cars for the mag here are my STANDARD 3rd gear rolling times.
40-60 - 2.2 seconds
50-70 - 2.39 seconds
60-80 - 2.58 seconds
Now I have had fitted the cat by-pass pipes and new pannel filter and the REVO map.
Tuned 3rd gear times all run the same as before
40-60 - 1.82 seconds
50-70 - 1.84 seconds
60-80 - 1.99 seconds
massive gains
as a note here are EVO R8 v10 roll on 3rd gear times
40-60 - 2.3 seconds
50-70 - 2.3 seconds
60-80 - 2.3seconds
and here are the mighty GTR 3rd gear times
40-60 - 2.1 seconds
50-70 - 2.1 seconds
60-80 - 2.1 seconds
Now that is impressive! Can I ask why you went for the TT? Apart from it being a quick car standard and even more so when mapped!
