2 bar map sensor
So I am ordered a Maggie this week and got ahold of my tunner this week and asked him about using a 2 bar map sensor he said I didnt need to get one. I have read its more for tunning I am only going to be maybe low 500 hp but can anyone explain why I wouldnt need the two bar. Is this really just a tuner preference I know that my tunner is VERY experenced with tunning ls motors. He said they are really only a must at big hp like 1000+. Please school me on this and explain what this is really all about.
