I have just purchased a new 2005 Accord SE Auto 4-cyclinder. My question is the Honda and Acura's have speed density sensor feeding info to the ECU to calulate fuel mixture. Toyota, Nissan,etc. just use the MAP and readily adjust to performance add on cold air intakes and cat-back exhaust. After reading up on the subject I guess I am petty much stuck with the stock set-up unless I add a fuel preesure regulator or a chip, of which both will void my warranty. I guess the only thing is to add a foam filter in the stock box. Do you guys have any ideas that will increase the engine pumping efficiency without reducing the gas mileage????????    

find someone who makes a chip for it.  try hondata  

Thanks for the website. I have always wanted to do things right the first time, instead of wasting money, time and not getting the results promised. Born Stevens Point Wis. along time ago, but still a child at heart. Thanks again.
