Hey bro look up the 12200411 pcm swap, or 411 pcm swap for short, Ive been reading up on it for about a week now and am very interested in doing it. I even found the 411 pcm out of a Chevy Express van, which has the stock map that we can run since the Express vans also came with L31's, on ebay for 90 bucks. And called around the junk yards in Alamo, and Donna to get the connectors, which they all had a bunch. The only thing thats holding me back is I hate messing with electrical stuff, and dont trust myself to rewire the 4 connectors on our trucks to the two connectors for the 411. And I have a blackbear tune for my "black box" and havent asked Justin if ill have to pay for a data cable tune after I do a swap.
