so I bought this car not too long ago and it ran pretty good for like a week and then my turbo (50mm eBay) locks up so I replace it. And my afr wasn’t working the whole time so I go ahead and replace the 02 and set a new base map for it cause It wasn’t tuned to begin with and I’d prefer to know that it has a somewhat good base map instead of blowing it up. Anyway I replaced the turbo and 02 and now she cuts out, it runs like 14 afr at idle and when load is on the engine it leans out and then loses all power but doesn’t die.

Aem fuel rail, rc750 injectors, 50mm eBay turbo, tail bov, and waste gate, s2 intake, and cams, supposedly has forged internals. Performance fuel filter, not sure on the pump but no issues until tune was changed so is it tune? Could it be bad plugs?
