Around an hour or so, I did mine in about 20 mins. Just take out the the stock air box, the pcm is in the air box(its gray with a wire harness pluged into it, dont unplug it), take it out and find a place to secure it. Unless you buy a pcm tray you'll have to find a way to secure the pcm to the engine bay( i used zip ties on mine). Then just follow the link I sent in the previous post. Oh and you did post a thank you.....thats what the "thanks" button is for lol.
