ca18det runnning rough

i just finished the install of my ca18det. i tool it for a drive and as soon as it sees boost it starts to spit and sputter until it registers vacuum again. i checked my IC piping for leaks and i check for vacuum leaks but could find none. any help would be appreciated.

thanks

Make absolutley sure that there are no leaks anywhere. Even a small one will give you those problems. If no leaks, it's your MAFS or the wiring of it.
