There is a tech article on this swap, as well as hundreds of posts about it. Good luck and you'll enjoy your new found power once you get the swap done!

Re: TBI-TPI conversion
I am just about finishing up my 91 tbi to 87 tpi maf swap! I had the harness converted by tpiparts.net! I would go there to change over your original harness because you have to repin a tpi to your tbi if you get a tpi one alone! BIG MISTAKE! Most of the swap would use your original sensors which is great for you! the tpiparts.net people know alot and they are very willing to work with you with trouble or questions! I have pics if you need help!
