Now this may seem like an odd question but since our variable cam timing on the 3.7l is dependant on the resistance of spring pressures of the valve springs, wouldn't adding overall stiffer valve springs necessary to fight valve float for higher rpm's and more lift substantially change how the TiVCT will behave? Our vct doesn't use oil pressure to change cam timing like a Honda... I haven"t read many posts on the 5.0's with aftermarket cams, but I think they have to use phase limiters in order to prevent fowling pistons into valves and I have no idea how much more complicated that makes the tune.
