I don't think this is a wastegate duty cycle issue. Upping the duty cycle will cause a boost overshoot (not quite a spike) which is what you are seeing when it maybe hits 17psi and then settles lower. BTW I also don't think the duty cycle can be programmed relative to elevation, so watch for overboost when you descend to lower elevations. You really need a different target boost number at higher elevations to maintain constant target boost... I think. My experience is with UTEC, but I think the concept is the same, as UTEC has duty cycle and a target boost map.
I'm not a tuning expert, but I play one on message boards.
