So, without seeing it...the Saab system adjust the boost level to the safest possible pressure (just short of pre-detonation) thousands of times per second, on a once per spark basis. Each compression stroke is analyzed by measuring the impedance of the fuel:air mixture while it's being compressed to decide when the spark will be fired, and boost and fuel mappings are based on that and other factors. Maybe this guy has improved on that process in which case he'll have no trouble getting a job, but if this is just some "increase base boost" or "increase max boost", it's not going to help. Saab already uses the max boost at all times, again as measured on a per-spark basis. Dave Hinz
