I dug into GLH #2 to see if it has the DC logic module to go along with the DC intercooler installed on it.

What I found was the stock GLH LM #5227369. the case of the LM has Stage III written on it in magic marker. It has the stock MAP sensor also.
When I removed the map sensor I saw it appears socketed and the chip has a label on it with "gotto S3" written on the label.
Anyone have any idea what this cal may be? There are no other labels or markings on the LM.
Everything works fine and the car runs strong. I'm just trying to get an idea of what was done be the prior owner.
It also has the engine bay mounted map sensor installed, but it is not plugged into the LM. This map is #5227492.

My guess is that it was a FWD cal for a guy named Gotto.

Or someone mis-spelled "ghetto" ? LOL...

Andy, how does it run with it? If it came with the DC intercooler then maybe its OK? If it doesnt run good, maybe try to find the DC "for use with DC intercooler" LM?

It runs pretty good as it is, short of a few vacuum leaks. I'm just trying to figure out what's what.
From what info I can find, the DC logic module swapped the firing order of the injectors. That's my biggest concern. I don't want to melt anything. I want to figure out if I need to swap the wires for the injectors or not.
I'll have to check out the plugs and see if any cylinders are running lean. I suppose I should check and see what injectors it has too.

Spent the afternoon under the hood and got things straightened out a bit. I eliminated the remote MAP sensor, fixed the vacuum issues and cleaned up a lot of electrical connections.
From the sparkplugs I see #1 and #4 are running rich. I get codes 52 and 35. The voltage on the O2 sensor was stuck at .52 v. After a while the O2 sensor started showing varying voltage and the fan relay started kicking in.
After a few rides around the block I checked the plugs again. #1 and #4 were still rich.
Could be dirty injectors.
I didn't go far enough to really make any speed, but the best I saw on the boost gauge was 10 psi.
I think a long ride and a bottle of Techron are in order here.
