I put a Corvette stock ls1 engine and 4l60e transmission into my recently built Buick Regal 1987. I use dbc throttle and truck 6.0 411 pcm. I couldn't find the right software. My coils and maf are also trucks. PCM blue red. I'm experiencing a boom in the exhaust at idle. My oxygen sensors are not installed.5.7 tune needs to be done. Can you help me?
Can you make the necessary changes?
