RPMís and gear also play a roll on boost numbers, the higher the rpms are the higher your boost numbers will be higher.
I donít know about your EDGE Evo but in the Insights menu you have a record section that keeps most of your pids max numbers, EGT, Boost, RPMs, ECT, etc, etc.
You can reset to 0 and start over.
If your chugging along 2200-2500 rpms your boost will be lower than if your in the 2800-3000 rpm range.
