Do you have the stock apexi map sensor?if so they're only good to about 28psi and maybe you're hitting the limit?

Imo: even though you're tuning on a dyno, be it a dynojet or load holding dyno dynamics, you still need to road tune it because those can never reflect real world conditions. And because the loads will be higher, your boost may be a little higher.
