hows that for a start and an example
precisely right, you lose half your VE table to resolution loss, I have heard it doesnt affect much, which is really great news for boosted 98 cars! and yes 50kpa now = 100 kpa..... etc. great assessment. I think with a nasty cammed and boosted car you might run in to some trouble though, but if its that nasty it might be time for a FAST, BS3, AEM setup.....

usually you also have to change your OLFA table to reflect teh same changes because it has a MAP referenced data, and your PE tables all go to different #'s as well...
timing maps change....there are just a ton of tables that will be effected by a 2 bar MAP on a PCM that has a 1 bar data set
