Hi Guys, bought my 2003 350gt A/T 6 months ago and am now considering minor mods. My questions are
1.will fitting a 5/16"plenum spacer, z tube & JWT pop-charger be a waste of time if i keep the exhaust stock.
2. If these mods are done is an engine tune recomended.
3. Would you recomend a dyno tune with such minor mods.
Thanks in advance
Gerard
