i actually do quite abit of highway driving but i guess the extra 500 rpm increase at highway speeds would be bearable for now haha
130kw was just a ball park figure, honestly cant remember why i used that in the first place..

At the moment my mind is more set on installing a ITR 4.4fd + LSD, using highways to whatever destination i need to go to puts me off the 4.7 Fd actually.

One more thing im curious about, in a dc2 vtir with i/h/e and the ITR gearbox, would tuning with a standalone ecu be required? or maybe a reflash would be sufficient? i was under the assumption that a change in gearing would decrease the performance of the car unless properly tuned, or is tuning only required and beneficial when internal work has been done, thanks again !
