    ls376/480 Tune for 02 Trans Am LS1

    Hello all,

    This is my first post on here and I want to see if anybody has had experience with a LS1 to LS3 swap such as the LS376/480 Crate motor. I need the stock tune file for it if possible for my LS1 PCM which will be in my 2002 Pontiac Trans Am LS1. The motor gets here Tuesday so I will be starting the motor hopefully by the next day. Any and all help would be greatly appreciated, thank you!

    I will be doing the following...

    - LS1 knock sensors on the side of the block w/ extensions
    - LS1 Map w/ extension
    - LS1 to LS3 cam sensor extension
    - Lingenfelter 58x to 24x conversion module
    - LS1 to LS3 injector adapters

    The only power mods aside swap mods will be the following...

    - Long Tube Headers
    - Full 3" exhaust w/ SLP LM1 muffler
    - SLP Lid

    I know this is a very old post and I'm sure you're up and running by now. I just ordered the LS376/480 for my 2001 Trans Am. Can you share what you are running for a program now? I'm basically stock except for the engine swap...no headers, full stock exhaust.

    Thanks in advance.
