Using a custom tune I would atleast use 2 degrees per 50 on 93 octane.

 

man my car would run backwards if i tried to mess with that lol i have tunercat but dont understand one thing im looking at. i pretty much burnt my money buying it lol

 

I'm using an MSD Digital 6 (300$ new) it has a setting to retard the timing only when the nitrous kit solenoids engage so when your not spraying it doesn't effect the timing, so you can leave the tuning alone.

You could find a retard box and a MSD 6A used for a little cheaper but I don't know a whole lot about setting those up.

 

well im swapping over to the delteq system so which one would i need?

 

Either should work, but how exactly to hook it up to the Delteq I don't know.
