Bank 1 (right side) is begging for fuel even though the ECM is going full correction on the fuel trim. You could switch O2 sensors from sides and check if 181 changes to a 189 failure code + verify fuel pressure. LUK

did the prob occur right after the mods or it ran fine then later on it developed the prob???

it started once i got all the parts back in my car. and thats when all the issues started and since then i cant get it working the same even with the igniition box disconnected
