Hi guys,
v6 charger don’t not response to any WOT spark advance modification
I found that : there is issue with Variable camshafts after couple runs and logs if vvt works fine engine perform very well either cams stay locked at 114 EX , 130 IN in cruising or WOT
NO Check Engine light
U0140 DTC only
Engine runs like champ
i did experiment guys
i unplugged IAT sensor Immediately check engine light came on
tried the same things on CAM phaser's nothing happen no Check engine light so, its bad PCM or what
i started thread here maybe someone had the same issue or by tuning we find another way to make it work
because without VVT that V6 perform like 4 cylinder engine
