so long story short i pulled my engine two seasons ago due to a cracked block. Got a new used engine with forged internals and put her back together, drained and refueled. Won’t go up on plane, hits 3,000-3,500 RPMS and is boggy, if i throw a few guys up in the bow or go out solo it will get on plane and max out at 4,000. I did a pull with it bogging down for about 30 seconds and plugs are so white they look brand new(fresh with engine swap). Except cylinder 6, which is golden brown. i checked fuel pressure and it’s fluctuating from like 40-50 pretty rapidly and checked compression and everything’s at 140ISH. Pulled codes and I’m getting 21 and 23 but both sensors tested fine. Intake temp sensor tested at 1.7K ohms which puts it at just over 100* and TPS tested at .65 closed and 4.56 open. Also tested the wires going back to the PCM and all is well. I’m going to check for intake leaks and replace my fuel filter to see what that does but I’m stumped as to why it’s throwing these two codes even tho they both tested fine. Any advice? Any way to verify that codes have been cleared from the system? I opened throttle to 100% multiple times and they still return
