I have a 5.3 LS that is tuned NA on corn. Usually run about 12.5 WOT on the gas scale (0.850 lambda) N/AI want to run about 150 to 200 through this little motor and was curious what is commonly used for AFR on corn with nitrous.This is a totally stock 5.3. Stock cam. Stock heads. Stock everything, just trying to spray our way to glory.
