Pcm doesnt need to know you are. Enrichment is commanded by TP Percent, and Spark is calculated by lbminVS RPM. I ran a one bar for 2 years when I was boosted. You run the one bar on a vacuum line that doesn't see boost like off the TB. You must however change some Bin's in your tune to run the 2 bar map
