2 codes after changing Imap sensor

[Hennessy]

After changing the IMAP sensor, and cleaning the egr differential pressure sensor, I had 2 codes come up code 124 pid 102 Intake manifold pressure high but above normal range

and code 687 pid 103 low turbocharger n1 speed

Cleared the codes but after researching the first one, it said it could derate the engine. anyone know what I missed? got 2 other codes but they are for the aftertreatment noX sensor outlet.

for those looking into these 2 sensors, the IMAP sensor is now 80, and the EGR differential is 242 from kenworth.
