Can Ivan's TRE works on 03 busa???

have been told that it will work, and yes it will use more fuel...

( still have not dedecided if I want one yet...)
(too much controversy on if it is really worth it)
part of the stock map uses more fuel down low....gears an' a TRE of some sort , IVANS,HOMEMADE,ATRE...etc
shouldn't use any more noticible amount of fuel , a good map will get ya runnin' better . Not too rich(like stock) not too lean either .

hav a good 1.....RSD.
