Yes, you can use the stock MAP sensor, but you have to make sure that you are not going to exceed the limits of your factory sensor under any conditions. For example, you may find yourself hitting a higher MAP under colder conditions. Also keep in mind that 23 psig is just a guideline as to the limit of the factory sensor - some factory sensors may not necessarily read that high (or become inaccurate near their limit). Just as if you maxed out the factory MAF sensor, maxing out the MAP sensor will cause you to go lean in SD mode as actual MAP is greater than reported MAP.
