I've always been impressed by what you've done on the other forums and it's funny it took me this long to find your actual build thread. Just read through and it's an amazing build, especially the wing that reminds me of Joe Dirt
Now you talk about how you have been messing with the mixture of water vs fuel on this car for years but you've never mentioned the timing. Have you been just doing little tweaks with timing or has the setup required retiming entirely even at the same boost? Such as when you first made your 17 psi base runs vs when you made them now and were much faster.
