72lb injectors. I doubt thats the issue.
The fuel pump is a new KJet Turbo pump. Should be putting out enough pressure/lpg's. Although I have not checked the pressure since my fuel rail doesn't have a valve.
Car was stage 0 and ran great prior to the +T so my issue generated after the fact...

Going off of your symptoms, I'd be looking into the fuel side of things. Spark blowing out creates more of a wall where power falls off and is a rich condition. What is the boost pressure when it goes lean? Maybe maxing out the AMM.

When I installed the Holset in my 245 and hit spark blowout, replacing the stock old ignition coil with an MSD ignition coil actually fixed the issue. Not sure of the condition of your current one, but that fixed it for me.

I'm running an MSD 6AL with Blaster SS coil. Never had any issues ever.

Whoops. Didn't see that. Good luck with the solution. Take a piss in the St. Johns river next time you're near it.

Hmm I wonder if it could be related to the fact the battery was relocated to the trunk and is grounded to Fran and not directly grounded to engine?
Dirty river it is!

How is the ground from the block to the frame? Also what gauge is it?

Ground was built using two copper ends and 0 gauge wire. It's grounded in stock location on the block running under to the frame rail where it's drilled:tapped with a bolt.

I still think it's the amm. I am going to install a legit 012 full 3" tonight and report back my results. That's the only additional part different (other than turbo, IC, BOV etc) added to the car from the last time it was driving perfectly.

Thanks for the advice and help. Keep it coming so we can see what this thing does and so I can get to painting the car!

The ghetto paint job will be accomplished by myself like everything else an seeing how people like my work, you will see how you can do it at home yourself too!

update:
I cleaned and installed an 012 AMM (3"). This did not help the issue at all.

I did happen to be looking over the engine and looking for something to just pop out at me hoping to see anything wrong or out of place just some sign of hope... Nothing did except one thing.

I noticed a couple of the pipes looked as if it slid out of the hoses. Even though it slid out some, there are those really tight beads I made so they wont blow off. Well i was able to tighten one of them easily and didnt fix the others. just the one. I drove it around one more time and as I started to drive off, I heard the BOV releasing air just driving normal like it was stuck open.. Thats strange. After I blipped the throttle it stopped.

Started in first and did a pull too redline. No issue, perfect afr's bust didnt notice the boost psi.
Shifted to second and WOT that beast. Went all the way up to 6000 rpms before it started its bucking and stuttering so it was a little smoother for some reason.
I did another pull starting in second and seemed to make it to the same rpm before doing it again. Shifted to 3rd same thing.

At this point I am unsure what boost pressure was but I know when im WOT in boost the afr's stay good around 11 but when it bucks, it goes full lean. I need a to set up a recording device and then review it since its so dang hard to watch all of these things at once.

Any idea's anyone? WG is new but not sure if its working right or not. BOV is new but seems as if it might be having issues too.Im getting frustrated and feel like giving up soon.

Sounds like the same issue I had. Sounds like your running out of fuel. What I ended up doing is swapping to a Walbro 255 in the tank and deleting the main pump. Then I used the stock wiring to trigger a relay and ran 10g wire to the pump from the power junction block through the relay and to the pump. And ran a appropriate 10g ground off the pump. I would give that a try

It runs solid 10 afr up to 23psi .......once it has more than a 1/8 tank of gas

Now we have new problems to solve; but solve them we will. This thing will be a beast before the end of the month.

It's a new intank pump. Any way to test it without removal?

intank pump test

but it could also be a leaky hose from the in tank pump to the pressure pump (leaking inside the tank)

are you using the factory wiring? Is it a oem pump? Upgrading the wiring to your pump is probably one of the cheapest and effective ways to make sure you have a good amount of fuel. Pumps aren't happy trying to pull high amperage at full load through a 30 year old 18 gauge wire
