    2001 2.5 200 efi running a 225 computer question

    I have been running a 225 efi computer for about a year and feel like performance is not as good as it was with the old 200 computer. Also my fuel usage is horrible. Is that 225 computer the reason? Thanks

    Yes the 225 has a fatter fuel curve because it needs it!!

    you can change computers or for a quicker cheaper fix you can try getting an adjustable fp regulator and dropping the psi a couple pounds but at 36-39lbs they are already pretty low

    Your engine is a 5 petal and the 225 is a 7 petal so it gets more air thus more fuel. I have ran the 225 on heavily modified 5 petal engines because I needed more fuel. Is there a reason you are running it instead of the 200? I have several if you are interested in trading to getting a 200 back on it. Just a thought.

    Without cut heads the computer is worthless....that setup with 150 lbs of compression works decent just don't expect an extra 5 mph out of the deal. 2-3 mph is bout all you might get from the experience's I've had with this setup.
