Getting frustrated. I cant get my AEM AFR dialed in 14.7 cruising. I am reading 15.2 in 5th gear. I finally got a new o2 sensor. I have changed pressure to 68 from 65 and still cant achieve the 14.7. WOT have not because I dont want to mess anything up. I can to dial in so I can WOT. Im tired of driving like grandma. I LOVE SPEED!!!
