    Just heard back from him and he said he changed the ETC from .0170 to .0123. Was this correct? I went from from a 3 bolt 75 mm to a 88mm TB and intake and then I went to a 90mm LS3. I was suprised that the WOT was only off by less than 2% when we check it. Any & all suggestions would be appreciated at this point. Between the intake, TB and TB adapter, I have $750+ invested and are seeing no results.
