so when i get high through the rpm range i get boost shutter or how ever you would like to word that boost moves up down quick then starts dropping really bad it didnt start doing this till i put the CIA on it and it popped the maf code someone has told me change the ecu out but anyone else have any suggestions let me know or what you have done or what ECU you would recoment

Coblasts

Have you by chance put the Maf in backwards or touched it with your fingers when you put it in.

How oily was the filter could cause issues.

Also what type of Cai did you install.

greenie899

no i havent didnt touch it had gloves on and the filter wasnt to bad and it was an typhoon intake
