This a friends 2010 pick up with 6.2L, installed a performance non-vvt cam. I have all the VVT codes taken care of , but the can't get the timing to hold true at WOT. I'm looking to get around 24deg timing at WOT, but timing modifiers or something is holding it back to approximately 19 degrees. Any help with the timing and Trq Mgt appreciated.
