    Intake valve temp I believe.

    What are you trying to do?
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    it all starts with a plastic lifter tray crack. now its a wiseco piston kit k0044xs +9cc. Summit stage 2 cam duration 278/287 lift 523/524. LS6 valve springs VVT Delete kit. 1 7/8 long tube headers 3 in collector thru 3 in dual x pipe exhaust. & of course HP tunner MPVI 2. I started watching youtube videos & alot of reading months ago. thought i had it down. my ecm has a different set of tables that no one has covered. Only tables under fuel are all IVT /eng temp the only VE table is under edit & its a Virtual Volumetric Efficiency table20200207_215933_resized.jpg20200207_215722_resized.jpg20200207_220010_resized.jpg20200207_220031_resized.jpg do i leave the open loop tables alone & just tune the VVE table

    Welcome to the E78 computer.

    There is not VE table, it's all VVE under the edit tab. The MAF and VVE control fueling as well as the torque model. The open loop stuff you can kinda just leave alone.
