I am thinking of swapping the PCM on my 99 K2500 Burb to a 0411, but wonder if the 98-00's are really that bad? Nothing can be much worse than my 99's 98-00 Vortec VCM can it?
I am not planning on custom OS's, just daily driving a 454 with a 4L80E. I am thinking of using the L21 front cover and crank sensor if I can install it without removing crank to put on wheel...
