you might reinstall the stock filter assembly and see if the code goes away after a few engine starts.
The code list that I have from Superchips says that a code p0245 is a T/supercharger Wastegate Solenoid A Low. No listing for a p0245A. I am lost as to a meaning.
See the other thread on P0245a.

P245A-EGR COOLER BYPASS CONTROL CIRCUIT /OPEN
Theory of Operation
The EGR Cooler bypass valve is used to bypass the EGR cooler when the engine is in an active regeneration mode. This is to prevent EGR cooler fouling. There are two portions to this diagnostic. At key on the ECM drives the control line low and then high and monitors the correct status response. Throughout engine operation looks for status response voltage to be within 5-8 volts. The EGR Cooler Bypass valve will send a signal between 1.0 and 1.7 volts. When this occurs the ECM logs a fault. The second portion of this diagnostic monitors Exhaust Gas Recirculation temperature. If the EGR Cooler Bypass valve was in bypass mode incorrectly, the exhaust gas recirculation temperatures would exceed a temperature limit; this condition will also trigger the fault. The ECM will light a MIL lamp immediately after this diagnostic runs and fails. The ECM will turn off the MIL lamp after the diagnostic passes in four consecutive drive cycles.
When Monitored:
Key on
Set Condition:
Voltage detected at status line is between 1.0 volt and 1.7 volts for more than 150 seconds consecutively.
Possible Causes
(F348) SMART POWER RELAY COIL FEED SHORTED TO BATTERY
(F348) SMART POWER RELAY COIL FEED OPEN CIRCUIT
EXHAUST GAS RECIRCULATION TEMPERATURE SENSOR ERRORS
COOLANT SYSTEM
EGR COOLER
(K671) STATUS CIRCUIT SHORTED TO GROUND
(K671) STATUS CIRCUIT SHORTED TO 5-VOLT SOURCE
ACTUATOR FAILURE
Hope this helps...

I had mine in for that on Monday. They replaced entire egr valve. I never noticed any performance difference. They did say there was a tsb though. Going to mail it to me. I already had all the current flashes
