    5.3 Mild cam tuning help

    Hello all, I am very new to hp tuners/tuning. I'm a Gm/Ford fleet mechanic however this is a whole new ball game to me. I would appreciate any insight,education or comments on getting my cam dialed in or pointers on where to start. Thank you in advance to anyone who takes the time to view the logs/help out. i am very much wanting to learn and become more familiar with the program and the parameters i don't normally deal with.


    What i have is a 5.3/4l60 that i rebuilt and swapped into a 1991 K2500

    Rebuilt 5.3

    862 heads
    LS6 valvesprings
    LS7 Lifters
    Doug Thorley Tri-Y headers (no Cats)

    1.) Idle set to 850 across the board(temporary)
    2.) Vats disabled
    3.) EVAP Deleted
    4.) RearO2's dtc's disabled

    Cam Specs:

    210/218 --0.510/0.510 @.050 on a 112 LSA

    In the video the truck is idling at the stock target idle speed( i hadn't changed tit to 850pm yet)

    Idle to Temp.hpl91 5.3 swap.hpt

    I also have not wired in the Park/Neutral signal wire to the pcm so my idle is set one way over the other regardless of being in park/gear. please take a look and let me know what you think. Thank you -Dustin

    i hope i posted what was needed, looks like im missing a config file
