I wouldn't do more than 12.5:1 for pump gas . Detonation is not your friend in FL .
Your going to need to pull a significant amount of timing for it to not ping on nitrous as well .
+1 you always taking care of all the questions... I have ran 12.5:1 LSvtec but never sprayed it. Although most people I raced swore I was on the bottle. Ran great till my brother missed 4th and dropped a valve.(no rev limit wit a damn ebay chip
) Takes me back 4+yrs ago. Just fillup on some real gas when you spay teh bitch.
