Cutting out problem Options

[TURBOWHT]

So my truck is still cutting out. If you guys done know its a 4g63 swapped dodge ram 50.

The truck was running good. never cut out. then one night. WOT the truck would creep alot and cut out. Fuel cut i assumed. Well the next day came and would cut out at 8psi. but would let me rev it from a stop just fine.

well started it up the next day and reved it up and now it cuts out from a stop. It shows im building 15psi just reving it up. Something is seriously not right. and i cant figure it out.

Here is what is done to the truck and what i have done.

The only aftermarket thing on the truck is a gm maft and greddy type s. and inline walbro fuel pump.

I put new plugs in it. bpr7es, thinking i fouled one and it cuts out high rpm. thats not the case.

I tightend down my intake manifold. for some reason the bolts backed out. So i thought that would fix it. nope. didnt still runs like crap. I checked the pipes and reseated them.but i havnt boost leak tested it since i dont have a tester.

Do you guys think its a boost leak? or something else? Could ecu cause it to cut out like this? because im pretty sure the caps were bad, it was smoking and smelled like ass one day. But i have no clue what the ecu does when it goes bad.

Anyhelp or something to check for would be great. thanks

So your thinking its prolly the ecu? I mean im going to replace it but just wondering what the problem really is.

Or do you think its a boost leak? regardless im going to do both anyways.
