    Default 4 degrees timing retard needed

    I have an 01 corvette ls1 , I need to retard the timing 4 degree's for my 100 shot wet nitrous. What table do I go to to retard it the 4 degree's? Any help would be highly appriciated. I am using EFI Live personal scan and tune updated to newest version...do not have wideband..The nitrous kicks in at WOT.

    You would generally go to the B5913 - High Octane table. Or if you are a Commercial or Workshop license owner you would probably want to use Custom OS V5. That allows you a table to retard timing when N20 kicks in. Could be worth the $150 upgrade cost if you aren't already Commercial

    Thanks, it probably would be a good investment.
