A real mans DSM :D, Introducing, the Starion

Well, that information is true, but somewhat misleading. The 86 ecu doesn't like it when you raise the boost past 13 or 14 psi, if you can even get there. Yes, you can take out the mass air sensor in SOME of the 86's. some cars don't care and might run better, others might run worse. There is a way to use a 1G mass air sensor with the 86 setup.

The 87-89 ecu, when used in conjunction with a 1G mass air sensor or a 1G maf translator allows for very high boost with no fuel cut (much higher than you could ever get with a 12a or 14g). The 86 does have a map sensor, but no AIT sensor. You can try unplugging the mass air sensor, but I'd wait till you have a wideband installed. Your stock boost gauge won't work either I bet.

The BCD or FCD should fix the boost cut or fuel cut problem. Either way, the 1G MAS would for sure fix it. I'm sure you can't hit fuel cut with a 12A anyway. I never did and remember that my 1987 had the same fuel-cut-happy ignition box.

You have to check what controller you have for the AIC, some of them can be rigged as MPI. That type can control each injector separately so you can make up for the couple lean intake runners and the couple rich ones. I thought TEP sold that kind so it's worth looking into.
If you are ever wantiong to make power; you have to up the size of the turbine wheel. The stock turbine wheel only belongs on the 12A. Even the 14G could really use the TD05H turbine. You an look at Chiplee's cam thread and he will show you that you can't make power on a TD05-20G, even at 25psi+
