I am pitting for a Grand Am Cup race team now, and the team will be running 4 Rx8s this season. Anyway, i talked to the team engineer (he sets up the cars and does all our tuning) and he had really good things to say about the new GReddy E-manage Ultimate and was able to tune a friends Rx8 with a GReddy turbo kit to about 350hp just for daily driving. I have been reading about it and decided it might be something good for FCs because it should allow us to remove the air flow meter and use a GReddy MAP sensor and wide band for tuning. Anyway, its just a thought.

Also I have a bunch of FC3s turbo II parts for sale @

I believe any EMS system will allow you to remove those parts... check the Engine Management forum on this site.
