Big Stuff 3

Hey, I am new to engine management systems and to mustangs for the most part. I can work on them a little but I don't have anywhere near the knowledge the people on this site have. I have a 1992 turbo mustang that is overheating. I thought I had the problem solved but it overheated again this weekend. I am thinking about taking it to a local shop but they are trying to push me into buying a Big stiff 3 system. They said the problem might be in the tune and they could be right. I just wanted to see what everyone here has to say about that. Is it worth spending $2100 for this system? Yes I have checked the typical stuff for overheating, thermostat, fans, head gasket etc. I more interested in whether or not I should buy the Big stuff 3 system. What is so good about it??? THANKS!!!

If I was going to spend that much on an efi system I would look at the pro m system. It was designed to replace the factory harness and ECU. Several people have used the system with very good results. The pro m system uses the factory sensors and there isn't any "upgrades or features" to buy. You can add coil near plug and that's about it.

The only things I know about big stuff 3 is. 1) it is one of the 3 systems the local dyno will tune. 2) it seems to be more race car oriented.

I'm sure there isn't anything wrong with bigstuff3 but id be sure this shop isn't just trying to sell you something.

Turbo cars require a pretty awesome cooling system.
