adjusting timing on boosted lt1

[MYLTWON]

Could someone please explain to me how lowering the baro update update gives you a bigger range to measure in the computer?

that alone doesn't. modifying when the baro value can be calculated prevents the PCM from adjusting baro up to whatever boost you're running in the real-world while it thinks it is actually still in the 1BAR range. expect other "funny" things to happen though, considering in a normal situation, the PCM will be calculating somewhere along the lines of 50kPa barometric.
