Like the title says. Changed fluids today, and got curious about the MAP sensor, since the car already had some obvious mods on it that had been changed back to near stock, and discovered that it's got a 3-bar sensor on it already. I'm positive that it at the least had a tune; is there a way to see if there's still one in there, and if so, whose? Thanks in advance!

The one on top of the intake is a 2 bar stock and the one before the throttle body is a 3 bar. If its tuned the 2 bar will be changed to a 2.5 or3 bar

Well, if there's a 3BAR on it, it's currently tuned ;) otherwise, it wouldn't run. Don't ask me how I know.

The best thing to do is go back to whoever had the car before you. If you can't do that, there might be some way to tell, but I don't think a new tuner would "read the stock file" if the stock fiile is not in it.

When you say it has a 3 bar on it, are you looking at the intake manifold or in front of the throttle body?

As said, the 3 bar is stock in front of the throttle body, intake manifold stock is a 2 bar.

Now that we have seen tuned cars with stock 2 bar MAP on the intake manifold, this distinction may not be 100% reliable.

100%. My first tune I asked Brad mentioned he could tune my SHO the stock two bar map. I let him and there was a big difference. I went with a 3 bar later because I became greedy and wanted E30 and all the boost my little turbos could muster.

That is true. However the presence of the intake manifold 2.5/ 3 bar map is still a dead giveaway. While not all 2bar are untuned, all 2.5/3bar are tuned. It's an easy 1st check.
