Weird jerking/fuel cut/backfire issue after fmic install

[2GEEZEY]

Okay so I finished my fmic install and I did a few pulls...

In WOT, it pulls then stops and jerks. My friend said it sounded like a backfire.
Could this be fuel cut?

I have the stock t25 with walbro 255, fuel labs afpr, stainless oil feed and apexi n1 catback with megan downpipe.catless.

When I rev to 5500k, or 6000k (even lower sometimes) Whitesh smoke comes out the exhaust. I pretty good amount. Am i Fueling to much!?

Help!!!

you might have a boost leak which may be causing you to hit fuel cut. do a boost leak test.

Create and use one of those. If that doesn't solve your problem then pull your plugs and check the gaps. Make sure they're all set to .029 inches. It will also not hurt to invest in some new BPR6ES's in case you haven't replaced yours in awhile.

just had midwest street performance do all my plugs and wires. so id have to rull that out

Why would you have someone do that for you?? Sounds like fuel cut to me, how much boost are you running? Do you have your bov recirculated?

Not sure how many pounds dont have my gauge in yet. I was rec. my bov. Im putting in a 16g right now. Ill let you know if its still doing the same thing

You should definitely put in that boost gauge before doing any mods, you have no idea how much boost you are running, and that is a bad thing.

I was rec. my bov.

Does this mean that you were recirculating before installing the new fmic and aren't now? If you aren't recirculating, you should be.

Sounds like a boost leak on the way and lack of research before doing mods.

Yes. and I still am recirculating my bov.
