When the car is idling it runs fine or if I rev it when stationary in will rev all the way through no issues. However as I drive and come off vac to boost the car dies back to idle. it then goes normal again until it comes off vac. It was running fine prior to this but I did hear a slight pop before it died. The vehicle is a stock vlt setup on a n/a motor running 10psi. Cant find anything obvious all the intercooler pipes etc are good. Think perhaps exhaust seal in the turbo? Any help would be good!

Have you tryed another afm?
