I have been doing a few pulls with my 02 Z, SC, cam, LT etc. Under WOT I am seeing a 12.2-11.8 range. I spoke to the company that sent me the tune and they told me to take away .5 under each RPM that needs it. Do they mean do to the PE table under fuel, where it says RPM and take away .5 where it goes lean? I am new to this so please bear with me. Thanks. They said the A/F should be in the 11.3-11.7 range.
