Car Jerks with a loud POP

[GSTdude06]

Loud POP and car jerks at high rpms. Boost Leak? To much fuel? What would cause this problem I keep on having??

Sounds like fuel cut. How much boost you running. Check for boost leaks, they can cause fuel cut also.

^^^ what he said. Also, watch the boost gauge. If it creeps up too high, this can also cause fuel cut. But the most common cause is a boost leak. Too much boost combined with adding a lot of fuel with an SAFC can also cause fuel cut because the ECU sees too much airflow.

What are ways to get rid of it? Can I like do something to the ECU like you can with the speed limiter?

sounds like fuel cut to me

look for boost leaks first. if that dont help turn the boost down. How much boost are you running. If you dont have any leaks and your boost isnt crazy high you need a fuel cut defencer or apexi safc. JUst in case you didnt already know you will hit fuel cut if you are running rich not lean and if the MAS signal is maxed out.

I have a SAFC but I dont have a logger so I havnt messed with it, all default settings. Im pretty sure im running rich and I have a leak at my TB but that will be fixed this weekend so ill find out if that was the problem. Thanks Yall!
