I'd noticed that occasionally I'd see the baro reading at 80kpa when I was using one MAP sensor for both MAP and Baro. I added a GM 1bar I had from another project and it seems to have cleared up some of the random bad fueling I was seeing. Wiring up the sensor was easy and, for me, the sensor was free. If I did it from scratch, though, I'd just get the MAP daddy from DIY. It'd make for a cleaner install.

Just thought I'd share what worked for me.

 

I'm actually thinking about building another MS while I'm up in AK with all the mods I want so when i get home I can just swap it with mine and sell the one I have. Install things like the mapdaddy and complete the boost and other mods I want to do.
