[QUOTE="Shaker1, post: 11448222, member: 4863"] I had something similar before I added my pulley and new tune. With a tail pipe sniffer and factory cats it was showing almost 13 A/F from 3500-6200. Never heard any detonation in 2 years that I ran that tune. Need a new dyno with the pulley and tune to get new numbers. I am tempted to add fuel at WOT, but everyone said it must be a bad reading, due to no detonation??? Anyone suggest a good tuner in northern Illinois? [/QUOTE]
