your computer is sending too much fuel because it thinks you are using 190cc instead of the 240cc that you put in there. i put the ex injectors in my car, and it gets horrible gas mileage. you will need to get it tuned to compensate for the extra fuel.
with all the modds in my sig, i still have the stock p05. it is not happy. there was a huge dead spot below 3k. talking to my tuner, he told me to go ahead and put them in and it did take care of my dead spot, but killed the mpg. he has my new computer and hondata and should be getting it back to me this week.
