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.

Jannetty says its a must as well. I believe it's to help the "remote" tuners really see what's going on, but I could be wrong? The part was only $40 anyways. It's a ZR1 3 bar map sensor btw. Good luck man

With the zr1 map sensor and your tune adjusted for it, you can also read boost through the obd2 port.

It hay be a tuner preference. He is probably doing a MAF only tune. With a Maggie you will not max out the MAF. With that being said, the proper way to maintain control over your tune is to have the 3 bar MAP sensor on the car. GM does this for a reason on the ZL1. It is a good idea to have it to tune the car correctly.
