Hey everyone im new here and to this whole realm of tuning etc. im currently starting on a el camino with a ls swap 5.3l lm7 and 4l60e out of a 01 tahoe. mainly here to get an idea on how to find the proper files to flash my pcm with a tune that will start and run with a few minor changes. im pretty good with all mechanical and most electronic devices if anybody has any info on g body swaps that they think may be helpful let me know! thanks in advance
