I have been struggling to find a 3 bar map sensor that works with efilive via a 411 ls1 computer.
Last year i tried a old style delphi 3 bar map and had nothing but issues. There was a blank area in the tune that i could not change and would go real lean every pass. Car drove low rpm fine and was reading boost over 20psi. Swapped back to my 2 bar map/tune and the car would run/pull fine.
I have been running all year 25+psi on my 2 bar and really need to get this figured out.

Which 3 bar map do you guys recommend/have experience with at high boost levels on the 411 pcm?

Thanks
