Oh!!!
I'm only running a 2.5bar (21psi or 250kpa) map sensor too, if your only mapped to 100/150kpa then i'm suprised you have not destroyed your engine!!
100kpa is 0psi (atmophereic pressure), so as soon as you go positive pressure your timing is not mapped at all, and when you go over 150kpa (7psi) your fuelling is not mapped either!!
All I can assume is that your 100kpa Advance cells are retarded enough to be safe and that you 150kpa fuelling cells are fuelling correctly for the maximum boost you run?!
