my friend has a '00 civic ex. he dyno'd his car with it stock...then went back to dyno after a few bolt-ons....he put an AEM V2 intake, AEM Pullies, Greddy header, and Greddy Catback....well there was a problem with the latest dyno...and this is where i need help. Im not to familiar with all the Air/fuel stuff but the guy said he was running rich...A/f was 12.1 when should be 13.1.....he said it was fine at part throttle tho 14.7.....what is the ideal A/F at WOT? and what is causing this problem...how to fix it? he did nothing but those bolt ons. thanks for the help. here's the dyno sheets...
