    Default 0411 in L29

    Has anyone done this yet? What are the differences vs the L31 and where would I get a base tune? I just bought EFI and want to start tuning my 99 K2500 soon.

    Cant say on the tune, but this PCM swap has been done numerous times. Lextech has the correct wiring diagrams, PM him for additional information.
