That's good news! Glad it wasn't anything catastrophic. ![Nod](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_nod.gif)
Some people around this forum are just thick headed. 13.5 AFR w/ E85 plus 4° knock retard was an obvious indication something bad was going on with that car. Yet people think just because its a modded Z06 it should win every race under any circumstance. LOL
Glad you're getting the lifter addressed. Should make a world of a difference.![Winky](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_wink.gif)

Thanks... we put it back on the dyno... its nice and safe now. 12.0 all the way across. I know its richer but we only saw a gain of ~5whp going to 12.5 so we decided its not worth it.
