    LQ4 stock tune with manual transmission

    Hi All. I?m doing a lq4 swap into a 79 gmc c3500 campers special and I?m using the original sm 465 transmission. I couldn?t find a stock lq4 tune with manual transmission in the tune repository. Any one know where I can find one? I have a p59 pcm form a 2005 Avalanche that I am using but it had a 5.3 with automatic. Any help would be appreciated. Thanks

    Eric

    the last 3 or 4 Ls swaps with t350/t400s we didnt change the tune at all for the 'manual' transmission installed.

    you could swap the OS over to late model camaro with a manual trans

    If it's DBC I'd try to find a F-body file to use.

    If its DBW I'd look for a vette file to use.
