Couple Of Codes

[01CUMMINS24]

A Friend Of Mine Has An 03 Duramax And His Check Engine Light Came On The Codes Are P102a Maf/low Input, P0234 Engine Over Boost, And P0700 Trans Contrl System. He Has A Superchip On It Other Than That It Is Stock. I Read In Other Threads That These Codes Could Be From The Programmer, Just Would Like Some Input On What To Do Or Check For!

Has the programmer been removed to see if it was the cause ?

No Its Still On. I Cleared The Codes And He Drove Yesturday And They Havent Came Back Yet.
