idles fine, white smoke when given fuel

[jwp130]

my dads 06 will start and idle just fine, when you give it fuel it runs rough wont really gain much rpm and smokes (white smoke) like someone set a pile of leaves on fire. my little matco scanner shows me 2 codes p0101 and p0102 both suggesting bad mass air flow sensor. ill try cleaning it but would those codes keep the charger from working
? seems like the charger is not working. was wondering if any of you guys could help me out with this as I don't have much experience with the dmax. thanks

Yea , I had a loose connection at my maf once and caused some issues like that. Might try cleaning it and checking the condition of the wires/connection. If its not getting a reading it can't tell how much boost its making so tje vanes may malfunction

cleaned egr, seemed stuck. runs much better now, still has a slight hesitation. smoked at first but seemed to clear up the longer it ran. no more check engine light.

I've had Duramax's with the same symptoms. Stuck open egr, blocked it and all good.

Is it an 06 LLY by chance?
