Updating 2 bar to 3 bar map sensor

I'm currently running a 2 bar SD tune on my turbo lsx. I'm maxing the MAP out now and think it's time to step up to a 3 bar map. I have a couple of the rectangle 3 bar old style GM sensors, are there better/more accurate ones out there or are these okay?

As far as moving my tune to 3 bar, from what I've read, it looks like the 2 & 3 bar maps operate on the same OS with the only changes being the scaling of the map sensor and that it will now pull data from the rest of the boost VE table and boost timing table? Is this correct? If so it looks like this will be a very simple swap....

Thanks

Yes, same COS... you just have to edit the MAP sensor scaling... you will have to make sure the Boost VE table is correctly populated from 200 kPa to 285 kPa (maximum Boost VE table axis value).

Great, Thanks Joe!
