I just changed my wimpy 3.23 gears to 3.73 to give the ol LS1 more "power on tap" Does anyone know what settings in EFI scan and tune I need to change? I am guessing the speedo needs to be adjusted but do I need to do any other settings for the change. Oh yeah....I also have a 3000 stall speed TCI converter....should I make any changes there or just let the converter do its thing? Also will be taking off the EGR (going to LS6 intake so won't be needing that crap !!) and will be taking out the AIR also. Does anyone know what settings to disable the AIR. I found the one for EGR.
Thanks for the help,
