First thing is first, to do any sort of tuning without being on a dyno, you need an air fuel ratio gauge. We sell them for only a few dollars above cost so that we can make sure everyone who wants to tune their own car actually buys and uses them.
All of us here on the forum can help you tune your car and teach you things but we need to know the most basic of basic info. Air Fuel Ratio. Without it, you might as well try to catch falling knives in the dark.
