Can some clarify for me the process of this. Do you have to plug the hole for the stock MAP and run a vacuum line to this new sensor? Then do you have to change the wiring up to accomodate the new sensor. I was going to order a 2 bar sensor but it appears that the sensor for the Meth kit is 2 bar so it should work right?
If you have the correct MAP, it should replace the OEM MAP you have and plug right into that OEM harness. You will have to pull off the rubber boot and swap it out. But its plug n play.
The Meth MAP will plug into a manifold port and will have it's own wiring.
LS1speed sells a pig tail that plugs into the stock connector for the stock map wiring harness. Just unplug the connector from the stock map and plug it into the new connector (pig tail) then plug in the other end to the new map. You will need to run a new vacuum line to the new map and plug it in. This is the way I did it with the 3bar map. You can leave the stock map in place...you are simply relocating the new map off of the intake manifold to an alternate location.
I believe GM sells a drop in replacement (but don't know for sure) that is a 2bar OEM part for the Cobalt. But as I stated I am not sure that it will plug directly into the back of the LSx intake.
The remote option is very easy...probalby the easiest mod I have ever done.
