2bar vs 3bar? looking at buying a 2bar map sensor for my turbo lsx fox build, i saw the 2bar is good up to 15psi, but i may eventually wanna go over that, will the 3bar map sensor work below 15psi?...i dont wanna have to buy another sensor if i can use the 3bar below 15psi

Sure, think about it, even a high-boost car has to idle and cruise off-boost a lot of the time, and your MAP still has to work to do the density part of your speed density calculations.
Most 2-bars are good to about 18-19 pounds of boost. If you aren't going higher, then the advantage is to stay with the smaller one, because it gives your greater resolution of manifold pressure in the boost range you actually drive. They all use approximately a 0-5Volt range, but the 3-bar has to save some of that range for all the way up to about ~30# of boost, where you will probably never run.

You can boost both the 2 bar and the 3 bar as much as you want to. The 2 bar will be a piece of cake to boost to 14#'s and the 3 bar is good to about 30#. Again, you CAN run as much boost as you want, but if you are going with more boost for each map senser than listed above, it will require a bit of extra tuning and experience.
In other words, a 2 bar map sensor you can run to say 25#'s of boost, but it will require much more in-depth tuning to get everything dialed in compared to the easy and very percise tune that could be had with the 2 bar map sensor and running say 12#'s of boost.
Ultimatly, 3 bar map sensor > 2 bar map sensor.
