Ive used a couple of different types,,,, the holley,,,,,a good little unit SDS (simple digital systems) and then the fast system,,,I used the fast system on a combo very similiar to yours,(85 tuneport 305),,,,,,,,IMO,,the fast is expensive BUT it does great,,,,I like the `idiot mode" the fast has,,,you tell it what you want and it will do it( A/F ratio),,,OR tuning can get high tech if you want,,,tuning each cylinder for individual timing and fuel,,,,I just used mine in the bank to bank mode

My SDS system was far less expensive BUT you had to make all the changes,,,,,at the time,,,it ran on a set program and didnt take readings from the O2 sensor,,,,it also had its own hand held programmer and didnt need a lap top like the others


if budget wasnt an issue,,,I would go with fast

Big Stuff 3 or 4. John Meaney has designed a system that is very expandable, easy to upgrade, and not painful to install/use. The downfall is the support and the users manual. FAST and Holley have the best online forums and tech support in my opinion. I have Motec, Accel, Holley, and BS3, and feel BS3 is geared more toward the GM engines. They all can be a royale with cheese pain in the *** though at times.

Right now I am playing with HPTuners on the factory computer in our V6 car.

When the budget permits and we step up to regular stock I will probably go with the Gen 3 or 4 unit from Big Stuff. Heard a lot of good reviews about the system, and the price is pretty nice.

I have looked into a DIY system called MegaSquirt. For the money it would work great, but I can see where i could majorly eff that up.

I'd go for the Spectre EMSPro or Megasquirt. Best buy for the money and lots of FREE help online or from manufacturer. We use and install these units with great success. I use the Spectre EMSPro on my J/FI Turbo coupe and plan on using Spectre unit on my Lt1 Stocker. We are also using one to straighten out shop twin turbo Mustang that was running PMS system with MAF. You can call me if you have any questions 601-371-0815. Spectre unit has builtin 4 bar map sensor, two step circuit, and wide or narrow band O2 sensor capability.
