If you look at them there is just not much to work with. Very thin skinned.

We didn't see any change after the YT's and yes this was from LS2portworks. I think maybe the 403 runs out the intake a little faster than the 6.0 Ed did. The GTO definitely showed more improvement.

Never tested it. I run 11.3:1 SCR and down around 8.4 DCR. Both by design. I also run 93 octane.
