Does anyone have any knowledge of ltft and stft for any aftermarket intakes? K&n, aem, srt... etc? I have an sri I built into to make a cai. My readings as far as fuel trims are a little more out of spec than I am comfortable with. I am trying to find readings on manufacturer made intakes for a bases as far as changing/tuning mine for the best. I'll take anything you have. Thanks.
