Sounds like you've addressed a lot of the heavy hitters already (fuel pressure regulator, spark plugs, cat converter). Careful with the MAF, esp if you're thinking of buying new. They're all made in China crap, and you're better off finding a used known working one instead. ECU would be last resort ...

Have any insights into modifying/hacking transmission software (would this be the TCM?) been made as a result of the extensive work done around the CEM? Specifically, modifying torque converter lock-up and slip parameters for TF-80SC's and their respective valve bodies. Pls forgive any ...
