Gidday im currently doing up a vt 5.0L wagon bit by bit and im looking at upgrading the throttle body as part of the process. I was looking at a 70mm one then came across a 90mm for around the same price. I was just wondering is it a case of the bigger the better or can this cause issues elswhere? Ive put on high flow cold air induction and a memcal chip im working on getting an exaust system made up right through because everything is just tired and stock standard. Id appreciate any feedback I can get as im pretty new to all this but loving it all the same cheers.
