    2010 6.2L Truck Cammed - Need help with Trq Mgt and Timing tables

    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.

    The High Octane Spark Table is commanding around 15 degrees at WOT (in the 4400 to 6800 RPM range). PE Spark Correction (EQ Ratio) is adding between 1 and 4 degrees, given that you are commanding around 1.18 EQ Ratio at WOT. This brings your final timing right in around 19 degrees at WOT (in the 4400 to 6800 RPM range), prior to KR being subtracted (if any).

    Thanks for the input and help. I swapped around several times with different timing tables and attempted to zero several of the adders. I guess I'll bump the timing up in the proper areas and give it another try next time he brings the truck back.
    I appreciate you taking the time to look over the tune.
