The map and tip sensors work together. (the tip is the white line) I also wanted to remove mine but I'am going to leave things alone.

i left mine on for a while, but come to find out the difference between the MAP signal and the TIP signal was causing my pcm to pull fuel at anything above 3800-4k rpm and go too lean for my liking. map sensor was seeing a modified signal due to my safc but the TIP was still seeing 25-26psi. pulled the white line and now fuel delivery is smooth all the way across the rpm range

my car is an 04 btw, with s2 no toys pcm
