Now when i say vtec,i mean VVTi-L,its just easier to say vtec,mybad..The XRS has a celica gts engine with a different computer,so VVTi-L don't come on until 7,000 rpm,where as the celica comes on at 6000 rpm...Red line at 8000-8500 rpm,correct me if am wrong Outphase.....find a way to make it come on at 6000rpm,you'll be set. Tq moves u of the line,3rd gear hp takes over...
